Description

Technical Field

[0001] The present application belongs to the technical field of optical amplifiers, and specifically relates to an optical amplifier and an optical coupler. Background Art

[0002] After a light source or light emitting source emits light (visible light, ultraviolet light, infrared light, X-ray), the radiation intensity distribution formed around the light source is generally determined. At this time, its irradiance generally satisfies the square inversion law in optics, that is, the intensity of the irradiance is proportional to the radiation energy intensity in that direction, inversely proportional to the square of the distance between the irradiated surface and the light source, and proportional to the cosine function of the angle between the light direction and the normal direction of the irradiated surface. If it is necessary to change the irradiation intensity law of the above irradiated surface, the general traditional method requires the use of an optical system (lens or reflector) to change the intensity distribution of the light source or light emitting source in that direction, thereby changing the irradiation intensity on the irradiated surface.

[0003] Sometimes, when the irradiance required on a larger plane is tens or hundreds of times the intensity of the irradiance formed by the light source or emission source on the plane, it is difficult to achieve the desired effect using the current traditional methods. At this time, the usual practice is to increase the light source or emission source by several times or tens or hundreds of times to achieve the required irradiance. This often results in a large volume and large equipment size; the power required is very large, resulting in a large waste of electricity, and the equipment will generate a lot of heat, causing the working environment temperature to be too high; in addition, such strong light radiation exposed to the outside may cause visual safety problems or other photobiological safety problems.

[0004] In real life, there are many times when we want to use less power consumption or radiation flux to produce higher irradiance without radiation leakage. However, there are not many technologies to achieve this goal, which leads to some practical problems.

[0005] In order to ensure the sterilization and virus killing of indoor spaces, many families and institutions use ultraviolet emission sources to kill germs and viruses. However, the common ultraviolet sterilizers at present usually expose ultraviolet rays directly to the outside, irradiating the room or the entire space area. During the ultraviolet radiation, the ultraviolet rays irradiate the entire space. In this way, due to the strong chemical properties of ultraviolet rays, the space generally cannot be occupied by people, which will affect people's normal production and life; on the other hand, ultraviolet rays extend to the entire space, and the spatial density distribution in the room is very small, so it generally takes half an hour to several hours to kill bacteria and viruses more comprehensively. In order to protect humans, some sterilizers now have added human body sensing systems. Once someone enters a safe distance, the system will automatically shut down to protect people who temporarily enter the space from ultraviolet damage. However, these cannot solve the problem that people cannot enter the sterilization space when the ultraviolet sterilizer is turned on and the sterilization time is very long. Summary of the invention

[0006] In view of the above-mentioned shortcomings or deficiencies of the prior art, the technical problem to be solved by the present application is to provide an optical amplifier and an optical coupler.

[0007] To solve the above technical problems, this application is implemented through the following technical solutions:

[0008] The present application proposes an optical amplifier, comprising a shell having an oscillation cavity, wherein the oscillation cavity is provided with a transmitting device of at least one target transmitting source, wherein the oscillation cavity is also provided with at least one set of relative reflection surfaces and at least one set of reversely relative reflection surfaces.

[0009] Furthermore, in the above optical amplifier, the oscillation cavity is provided with at least one first channel for introducing gas, liquid or other fluid.

[0010] Furthermore, in the above optical amplifier, at least one second channel for conducting gas, liquid or other fluid is provided in the oscillation cavity.

[0011] Furthermore, in the above optical amplifier, the diameter of the second channel is not greater than 1 / 2 of the maximum size of the oscillation cavity.

[0012] Furthermore, in the above optical amplifier, the inner wall of the shell is coated with a first reflective layer, and the light reflection efficiency of the first reflective layer to the target emission source is not less than 50%.

[0013] Furthermore, the above optical amplifier further comprises a first cover plate and a second cover plate arranged on the shell, the outer surfaces of the first cover plate and the second cover plate are coated with a first light absorbing layer, and the light absorbing efficiency of the first light absorbing layer is not less than 70%.

[0014] Furthermore, in the above optical amplifier, the inner surfaces of the first cover plate and the second cover plate are coated with a second light absorbing layer, and the light absorbing efficiency of the second light absorbing layer is not less than 70%.

[0015] Furthermore, in the above optical amplifier, the first cover plate and the second cover plate are both provided with the first channel for introducing gas, liquid or other fluid.

[0016] Furthermore, in the above-mentioned optical amplifier, a first partition plate and a second partition plate are also provided in the oscillation cavity, and the first partition plate and the second partition plate are both provided with through holes; the first partition plate and the second partition plate are coated with a third reflective layer on one side facing the center of the oscillation cavity, and the reflective efficiency of the third reflective layer is not less than 50%.

[0017] Furthermore, in the above optical amplifier, a third light absorbing layer is coated on one side of the first partition and the second partition away from the center of the oscillation cavity, and the light absorbing efficiency of the third light absorbing layer is not less than 70%.

[0018] Furthermore, the above optical amplifier further comprises a first outer protrusion and a second outer protrusion arranged on the shell, and the internal cavity of the first outer protrusion / the second outer protrusion is connected to the oscillation cavity.

[0019] Furthermore, in the above optical amplifier, inner surfaces of the first outer protrusion and the second outer protrusion are coated with a fourth reflective layer, and the light reflection efficiency of the fourth reflective layer is not less than 50%.

[0020] Furthermore, in the above-mentioned optical amplifier, the target emission source includes infrared light, ultraviolet light, visible light or X-ray.

[0021] Furthermore, in the above-mentioned optical amplifier, the emitting device includes a low-pressure gas discharge light source, a halogen light source, an LED light source, a high-pressure gas discharge light source, a laser light source or an X-ray generator.

[0022] Furthermore, in the above-mentioned optical amplifier, at least one groove is provided on the outside of the shell, which can reflect the light irradiated vertically by the transmitting device to the position of the oscillation cavity to the side, so that the light will not be reflected by the oscillation cavity to the transmitting device itself, causing it to produce a larger self-absorption phenomenon.

[0023] The present application also proposes an optical coupler, comprising the above optical amplifier and an optical fiber core, wherein the optical fiber core is arranged on the second channel.

[0024] Compared with the prior art, this application has the following technical effects:

[0025] The present application can form a strong light volume irradiance in a semi-enclosed space with a very small radiation dose, in which photons oscillate back and forth multiple times until they hit bacteria, viruses or dust particles.

[0026] This application can get rid of the limitation of the inverse square law from the light source to the illuminated surface, and can create a high irradiance intensity space with an irradiance intensity that is tens to hundreds of times higher than the traditional method, achieving the effect of rapid sterilization and disinfection. It can basically ensure that the ultraviolet radiation dose received by the bacteria or viruses passing through the cavity within 1 second reaches dozens or hundreds of times its lethal dose, which can achieve the effect of killing bacteria or viruses in seconds; at the same time, due to the back and forth oscillation of photons, the body irradiance intensity formed by the disinfection space is very high, and it is strong in all directions. At this time, assuming that the diameter of a bacterium or virus is R, the area where the bacteria or virus receives the ultraviolet dose is 4πR 2 Therefore, in this case, the ability of bacteria or viruses to receive radiation doses will directly increase by about 4 times (in the usual sterilizer model, light only irradiates bacteria or viruses from one direction, so the surface area receiving radiation is approximately equal to πR 2 ), which also greatly improves the killing effect of bacteria and viruses.

[0027] The photon oscillation cavity of the present application is designed to be closed, and photons can hardly overflow the oscillation cavity, so that photons harmful to the human body will find it difficult to overflow the sterilization and disinfection space and will be strictly confined therein, so as not to cause harm to people or organisms outside the oscillation cavity, allowing people to move and work freely in the space outside the oscillation cavity without affecting their lives.

[0050] The concept, specific structure and technical effects of the present application will be further described below in conjunction with the accompanying drawings to fully understand the purpose, characteristics and effects of the present application.

[0051] Embodiment 1

[0052] like Figures 1 to 4 As shown, in one embodiment of the present application, an optical amplifier includes a housing 1, wherein the housing 1 has an oscillating cavity, wherein the oscillating cavity is provided with a transmitting device of at least one target transmitting source, wherein the oscillating cavity is also provided with at least one set of opposite reflecting surfaces and at least one set of oppositely opposite reflecting surfaces. This embodiment can form a strong light volume irradiance in a semi-enclosed space with a very small radiation dose, wherein photons oscillate back and forth multiple times until they hit bacteria, viruses or dust particles.

[0053] Among them, the above-mentioned at least one set of oppositely opposed reflecting surfaces can be a device that provides oscillation service for the oscillation of radiation energy (infrared, ultraviolet, visible light, X-rays); the target emission source (infrared, ultraviolet, visible light, X-rays) can be between at least one set of oppositely opposed reflecting surfaces, or outside at least one set of oppositely opposed reflecting surfaces.

[0054] If the target emission source (infrared, ultraviolet, visible light, X-ray) is outside at least one set of relative reflective surfaces, the energy of the target emission source can be introduced between at least one set of relative reflective surfaces through an optical path. If the optical path is not used, then at least the energy of the target emission source needs to be directly irradiated onto at least one of the reflective surfaces.

[0055] Among them, the energy of the target emission source in this embodiment must have the characteristics of wave-particle duality, so that it can be reflected on the reflection surface by utilizing its wave property; and by utilizing its particle property, it can be regarded as a bullet to bombard the target particles in the fluid flowing through its oscillation cavity.

[0056] In this embodiment, the target emission source includes infrared light, ultraviolet light, visible light or X-ray. Figures 1 to 4The diagram shows a case where four target emission sources are provided, namely target emission source 41, target emission source 42, target emission source 43 and target emission source 44. According to actual needs, at least one, two, three or even more target emission sources may be provided, and the number of target emission sources and the selection of specific light may be designed according to the radiation intensity of the inner cavity to be achieved, which is highly flexible.

[0057] The emitting device includes but is not limited to one or more of a low-pressure gas discharge light source, a halogen light source, an LED light source, a high-pressure gas discharge light source, a laser light source or an X-ray generator.

[0058] Among them, the above-mentioned shell 1 can be made of metal, plastic, ceramic and other materials. If the target emission source 41 or the target emission source 42 or the target emission source 43 or the target emission source 44 contains X-rays, the shell 1 is preferably made of lead material.

[0059] The oscillation chamber is provided with at least one first channel 51 for introducing gas, liquid or other fluid. The gas, liquid or other fluid to be treated is input into the oscillation chamber through the first channel 51 for sterilization and disinfection, and then is discharged from the second channel 52 provided at the other end.

[0060] If necessary, a circulation system connected to the first channel 51 and the second channel 52 is further configured to achieve the processing of gas, liquid or other fluids.

[0061] The inner wall of the housing 1 is coated with a first reflective layer, and the reflective efficiency of the first reflective layer for the light emitted by the target emission source 41 or the target emission source 42 or the target emission source 43 or the target emission source 44 is not less than 50%. Preferably, the first reflective layer has a reflective efficiency of greater than or equal to 60% for the light emitted by the target emission source 41, target emission source 42, target emission source 43, or target emission source 44, preferably, the first reflective layer has a reflective efficiency of greater than or equal to 70% for the light emitted by the target emission source 41, target emission source 42, target emission source 43, or target emission source 44, preferably, the first reflective layer has a reflective efficiency of greater than or equal to 80% for the light emitted by the target emission source 41, target emission source 42, target emission source 43, or target emission source 44, preferably, the first reflective layer has a reflective efficiency of greater than or equal to 90% for the light emitted by the target emission source 41, target emission source 42, target emission source 43, or target emission source 44, preferably, the first reflective layer has a reflective efficiency of greater than or equal to 92% for the light emitted by the target emission source 41, target emission source 42, target emission source 43, or target emission source 44. The closer the above-mentioned reflective efficiency is to the theoretical limit of 100%, the better.

[0062] The first reflective layer can be realized by aluminum, copper, gold, silver, tin, silicon or a multi-layer silicon-carbon coating or plating.

[0063] The first reflective layer may form a plurality of reflective surfaces which are arranged opposite to each other.

[0064] This embodiment further includes a first cover plate 21 and a second cover plate 22 disposed on the housing 1, and the outer surfaces of the first cover plate 21 and the second cover plate 22 are coated with a first light absorbing layer, and the light absorbing efficiency of the first light absorbing layer is not less than 70%. Preferably, the light absorbing efficiency of the first light absorbing layer is greater than or equal to 80%; preferably, the light absorbing efficiency of the first light absorbing layer is greater than or equal to 90%; preferably, the light absorbing efficiency of the first light absorbing layer is greater than or equal to 92%.

[0067] Wherein, the second light absorbing layer is preferably made of black or dark material.

[0068] like Figure 2 As shown, the first cover plate 21 and the second cover plate 22 are both provided with the first channel 51 for introducing gas, liquid or other fluid.

[0069] The oscillation cavity is also provided with a first partition plate 31 and a second partition plate 32. The first partition plate 31 is provided with a through hole 61, and the second partition plate 32 is provided with a through hole 62. The through hole 61 and the through hole 62 are channels for the introduction or export of gas, liquid or other fluids. The first partition plate 31 and the second partition plate 32 are coated with a third reflective layer on one side facing the center of the oscillation cavity, and the reflective efficiency of the third reflective layer is not less than 50%. Preferably, the light reflection efficiency of the third reflection layer to the target emission source 41 or the target emission source 42 or the target emission source 43 or the target emission source 44 is greater than or equal to 60%, preferably, the light reflection efficiency of the third reflection layer to the target emission source 41 or the target emission source 42 or the target emission source 43 or the target emission source 44 is greater than or equal to 70%, preferably, the light reflection efficiency of the third reflection layer to the target emission source 41 or the target emission source 42 or the target emission source 43 or the target emission source 44 is greater than or equal to 80%, preferably, the light reflection efficiency of the third reflection layer to the target emission source 41 or the target emission source 42 or the target emission source 43 or the target emission source 44 is greater than or equal to 90%, preferably, the light reflection efficiency of the third reflection layer to the target emission source 41 or the target emission source 42 or the target emission source 43 or the target emission source 44 is greater than or equal to 92%. The closer the above light reflection efficiency is to the theoretical limit of 100%, the better.

[0070] The third reflective layer can be realized by using aluminum, copper, gold, silver, tin, silicon or a multi-layer silicon-carbon coating or plating.

[0071] The first partition plate 31 and the second partition plate 32 are coated with a third light absorbing layer on one side away from the center of the oscillation cavity, and the light absorbing efficiency of the third light absorbing layer is not less than 70%. Preferably, the light absorbing efficiency of the third light absorbing layer is greater than or equal to 80%; preferably, the light absorbing efficiency of the third light absorbing layer is greater than or equal to 90%; preferably, the light absorbing efficiency of the third light absorbing layer is greater than or equal to 92%.

[0072] The third light absorbing layer is preferably made of black or dark-colored material.

[0073] To further enhance the light reflection effect, the present embodiment further includes a first convex portion 71 and a second convex portion 72 disposed on the housing 1, and the internal cavity of the first convex portion 71 / the second convex portion 72 is connected to the oscillation cavity. The first convex portion 71 and the second convex portion 72 are preferably hemispherical structures.

[0074] The inner surface 711 of the first outer protrusion 71 and the inner surface 721 of the second outer protrusion 72 are both coated with a fourth reflective layer, and the light reflection efficiency of the fourth reflective layer is not less than 50%.

The closer the above light reflection efficiency is to the theoretical limit of 100%, the better.

[0075] The fourth reflective layer can be realized by aluminum, copper, gold, silver, tin, silicon or a multi-layer silicon-carbon coating or plating.

[0076] like Figure 4 As shown, the working principle of this embodiment is as follows:

[0077] The energy emitted by target emission source 41, target emission source 42, target emission source 43, and target emission source 44 (infrared, ultraviolet, visible light, and X-rays) is radiated outward in the form of photons (infrared, ultraviolet, visible light, and X-rays) by the four target emission sources 41, target emission source 42, target emission source 43, and target emission source 44, respectively.

[0078] A portion of the light energy I is emitted by the target emission source 41 or the target emission source 42 or the target emission source 43 or the target emission source 44 and irradiates the inner surface of the first partition 31 or the second partition 32. Due to the high reflectivity of the inner surface of the first partition 31 or the second partition 32 to the light, only a very small amount of energy will be absorbed by the inner surface of the first partition 31 or the second partition 32, and most of the energy will be reflected.

[0079] A portion of the light energy II is emitted by the target emission source 41 or the target emission source 42 or the target emission source 43 or the target emission source 44 and irradiates the inner surface of the shell 1. Due to the high reflectivity of the inner surface of the shell 1 to the light, only a very small amount of energy will be absorbed by the inner surface of the shell 1, and most of the energy will be reflected.

[0080] A portion of the light energy III is emitted by one of the target emission sources 41 and irradiates the inner surface of the other three target emission sources 42 or target emission sources 43 or target emission sources 44. Since the other three target emission sources 42 or target emission sources 43 or target emission sources 44 can transmit the energy emitted by the emission source (infrared, ultraviolet, visible light, X-ray), most of the energy III can pass through the other three target emission sources 42 or target emission sources 43 or target emission sources 44 (a small portion of the energy will be absorbed by the target source) and irradiate a certain inner surface of the shell 1. A very small portion is absorbed by the inner surface of the shell 1, and most of the energy will be reflected. Among them, one of the above-mentioned target emission sources is described by taking the target emission source 41 as an example, which can be any one of the four target emission sources.

[0081] Of course, some of the energy will pass through the through hole 61 of the first partition 31 or the through hole 61 on the second partition 32 and illuminate the inner surface of the first outer protrusion 71 or the second outer protrusion 72. Due to the strong reflectivity of the inner surface of the first outer protrusion 71 or the second outer protrusion 72, a small part of the energy will be absorbed by the inner surface of the first outer protrusion 71 or the second outer protrusion 72, and most of the energy will be reflected into the core inner cavity (i.e., the cavity formed by the inner surface of the shell 1 and the inner surface of the first outer protrusion 71 or the second outer protrusion 72). Some of the optical fibers VI that are not reflected into the core inner cavity will illuminate the outer surface of the first partition 31 or the second partition 32. Due to the strong absorption of the outer surface of the first partition 31 or the second partition 32, most of the energy is absorbed. Very few of them can illuminate the inner surface of the first outer protrusion 71 or the second outer protrusion 72, and due to the strong absorption of the inner surface of the first outer protrusion 71 or the second outer protrusion 72, almost all of the energy is absorbed.

[0082] The energy coming out of the core cavity is very small because the through hole 61 of the first baffle 31 or the through hole 62 on the second baffle 32 is relatively small and the first cover plate 21 is relatively close to the first baffle 31, or the second cover plate 22 is relatively close to the second baffle 32. Therefore, only a very small amount of energy can escape and directly irradiate the inner surface of the first outer protrusion 71 or the second outer protrusion 72. Due to the strong absorption of the surface, only a very small amount will be reflected to the outer surface of the first baffle 31 or the second baffle 32. Due to the strong absorption of the outer surface of the first baffle 31 or the second baffle 32, the energy is almost completely absorbed. Among them, only a very small amount of energy has the opportunity to reach the second channel 52 hole and escape from the core cavity.

[0083] Therefore, only a very small amount of the photon energy emitted by the target emission source 41 or the target emission source 42 or the target emission source 43 or the target emission source 44 can escape from the core inner cavity through the hole of the first channel 51 provided on the first cover plate 21 or the second cover plate 22 .

[0084] The energy reflected in the core inner cavity will once again shine on the inner surface of the shell 1, the inner surface of the first cover plate 21 or the second cover plate 22, or the target emission source 41 or the target emission source 42 or the target emission source 43 or the target emission source 44, and most of them will once again be reflected to other parts of the core inner cavity.

[0085] This cycle continues endlessly, causing the photon energy to oscillate continuously in all directions within the core cavity.

[0086] This embodiment increases the utilization efficiency of photons by tens or hundreds of times through continuous oscillation in the core cavity, just like a car turbine can greatly improve the utilization efficiency of fuel and output more power. Through the above working method, the photon radiation illumination value can be enhanced by tens or hundreds of times in any direction. Figuratively, this technology is called light turbine technology.

[0087] Using simulation software, the effects in the visible light part were simulated and calculated for two situations: one in which there was no optical turbine structure and the other in which optical turbine technology caused photon oscillations in the core cavity.

[0088] In this embodiment, two test planes are established. The first test plane is in the core inner cavity and parallel to the axial direction of the four target emission sources 41 or the target emission source 42 or the target emission source 43 or the target emission source 44 (see Figures 5 to 8 ), the second test plane is perpendicular to the axial direction of the four target emission sources 41 or the target emission source 42 or the target emission source 43 or the target emission source 44 (see Figures 9 to 12 ).

[0089] in, Figure 5 This is a simulation diagram without the effect of the light turbine structure. At this time, all structures except the target source of the present application are set to 100% absorption, simulating the irradiance inside the oscillation cavity when there is no present application; Figure 6 This is a diagram of the illumination situation when the lightless turbine structure is in effect. At this time, all structures except the target source of the present application are set to 100% absorption, simulating the irradiance situation inside the oscillation cavity when there is no present application; Figure 7 This is a simulation diagram with the light turbine structure, that is, the light irradiance of the same target source to the same test area when the application function is added; Figure 8 This is the illumination diagram with the light turbine structure in effect, that is, the light irradiance of the same target source to the same test area when the function of this application is added. Through the above comparison, it can be seen that in the parallel direction, when the internal reflection coefficient of the light turbine structure is 92%, the average irradiance value in the core cavity with the light turbine structure will reach 10.59 times the average irradiance value in the core cavity without the light turbine structure.

[0090] The simulation test results of the test plane perpendicular to the axial direction of the four target emission sources 41 or the target emission source 42 or the target emission source 43 or the target emission source 44 are as follows:

[0091] in, Fig. 9 This is a simulation diagram without the effect of the light turbine structure. At this time, all structures except the target source of the present application are set to 100% absorption, simulating the irradiance inside the oscillation cavity when there is no present application; Fig.10 This is a diagram of the illumination situation when the lightless turbine structure is in effect. At this time, all structures except the target source of the present application are set to 100% absorption, simulating the irradiance situation inside the oscillation cavity when there is no present application; Fig.11 This is a simulation diagram with the light turbine structure, that is, the light irradiance of the same target source to the same test area when the application function is added; Fig.12 This is a diagram of the illumination situation when the light turbine structure is in effect, that is, the light irradiance situation of the same target source on the same test area when the function of this application is added.

[0092] From the above comparison, it can be seen that in the vertical direction, when the internal reflection coefficient of the optical turbine structure is 92%, the average irradiance value in the core cavity with the optical turbine structure will reach 11.01 times the average irradiance value in the core cavity without the optical turbine structure.

[0093] Combining the simulation calculation results in the above two directions, it is obvious that this embodiment will bring a significant improvement effect on the irradiance value in the core cavity. Moreover, the irradiance value in the core cavity is significantly improved in all directions. And if the internal reflection coefficient is increased to more than 92%, the increase ratio of the average irradiance will be greatly improved.

[0094] like Fig.13 As shown, in this embodiment, a plurality of grooves 11 are arranged on the outer wall of the housing 1 , wherein the grooves 11 are recessed toward the interior of the housing 1 .

[0095] The groove 11 provided above can increase the energy of the light emitted by the target emission source 41, the target emission source 42, the target emission source 43, or the target emission source 44 to the oscillation cavity, so as to improve the energy extraction rate of the target source. Specifically, the groove 11 can reflect the light irradiated vertically from the target emission source 41, the target emission source 42, the target emission source 43, or the target emission source 44 to the position of the oscillation cavity to the side, so that the light will not be reflected by the oscillation cavity to the emission device itself, causing it to produce a greater self-absorption phenomenon.

[0096] The groove 11 can also provide a mounting position for the target emission source 41, the target emission source 42, the target emission source 43, or the target emission source 44. For example, it can be used to mount a gas discharge point light source, a tungsten filament light source, or an LED light source.

[0097] Embodiment 2

[0098] like Fig.14 and Fig.15 As shown, the difference between this embodiment and the above-mentioned embodiment 1 is that the target emission source in this embodiment adopts at least one LED light source.

[0099] Among them, the LED in the above-mentioned LED light source passes through the shell 1 and extends into the oscillation cavity, and the driving mechanism and control circuit electrically connected to the LED are arranged outside the shell 1. The above-mentioned arrangement can effectively prevent the oscillation cavity from being damaged or aged due to the strong light exposure in the oscillation cavity.

[0100] In this embodiment, the target emission sources are preferably set to five, specifically target emission source 41 , target emission source 42 , target emission source 43 , target emission source 44 and target emission source 45 .

[0101] Embodiment 3

[0102] like Fig.16 and Fig.17 As shown, this embodiment is an improvement on the first embodiment, wherein the target emission source in the first embodiment is arranged in a vertical direction, while the target emission source in this embodiment is arranged in a horizontal direction.

[0103] Among them, the main structure 131 of the oscillation cavity, the target emission source 134, the target emission source 135, the target emission source 136 and the target emission source 137 can be infrared, ultraviolet, visible light, or X-ray emission sources.

[0104] The first channel 132 and the second channel 133 for gas or liquid to flow in and out have a reflective coating on their outer surfaces and a light-absorbing material on their inner surfaces, and are dark or black in color.

[0105] The first channel 132 and the second channel 133 are respectively arranged to penetrate the shell, so as to realize the introduction and export of liquid, gas or other fluids.

[0106] The working principle of this embodiment is as follows:

[0107] Most of the light emitted by target emission source 134, target emission source 135, target emission source 136 or target emission source 137 (infrared, ultraviolet, visible light, X-ray) is reflected at the inner surface of shell 131 and the outer surfaces of first channel 132 and second channel 133, and then is emitted to the inner surface of shell 131 and the outer surfaces of first channel 132 and second channel 133 again, thus repeating continuously and performing continuous reflection oscillation, finally forming a very strong irradiation intensity, which is several times or even dozens of times that of when there is no such device.

[0108] If gas or liquid flows into the first channel 132 and the second channel 133 at this time, the gas or fluid will be irradiated by light that is several or dozens of times the target emission source (infrared, ultraviolet, visible light, X-ray) oscillated and amplified by the present embodiment.

[0109] Embodiment 4

[0110] like Fig.18 and Fig.19 As shown, the above embodiment three Fig.16 The target emission source 134, the target emission source 135, the target emission source 136 or the target emission source 137 (infrared light, ultraviolet light, visible light, X-ray) in the Fig.18 and Fig.19 Several target emission sources 184 (infrared, ultraviolet, visible light, X-ray) can also be realized Fig.16 The effect in. Fig.18 and Fig.19 The target emission source 184 is an LED emission source, and the LED irradiates the emitted light into the interior of the main structure 181 through the small hole of the main structure 181. The PCB, drive and control device of the LED are all located outside the main structure 181.

[0111] The first channel 182 and the second channel 183 for gas or liquid to flow in and out are coated with a reflective coating on the outer surface and a light-absorbing material on the inner surface, and the color is dark or black. The first channel 182 and the second channel 183 are respectively set through the shell to achieve the introduction and export of liquid, gas or other fluids.

[0112] Embodiment 5

[0113] The present application also proposes an optical coupler, such as Fig. 20 and Fig.21 As shown, it includes the optical coupler mentioned above. Specifically, the optical amplifier is not provided with the above-mentioned at least one first channel for introducing gas, liquid or other fluid into the oscillator.

[0114] In this embodiment, at least one second channel for guiding out gas, liquid, other fluid or light is provided in the oscillation cavity, wherein the diameter of the second channel is not greater than 1 / 2 of the maximum dimension of the oscillation cavity.

[0115] The main structure 201 of the optical coupler constitutes a highly enclosed space with only the optical fiber core as a single exit for light. Its inner surface is coated with a reflective coating of the target emission source (infrared, ultraviolet, visible light, X-ray), and its reflective layer has the same technical features as the first reflective layer in the above-mentioned embodiment 1.

[0116] The first component 204 is an LED or laser diode target emission source (infrared, ultraviolet, visible light, X-ray), and the second component 202 is an optical fiber core.

[0117] The working principle of this embodiment is as follows:

[0118] The first component 204 is a light source (infrared, ultraviolet, visible, X-ray) of a target emission source (LED, laser diode), and a small portion of the light is irradiated onto the optical fiber core of the second component 202 and enters the optical fiber.

[0119] The rest will be reflected on the highly enclosed inner wall of the main structure 201. Due to the high reflectivity of the inner wall of the main structure 201, most of them will be directed into the core cavity formed by the main structure 201, continue to oscillate and emit to other places, and only a small part will be absorbed by the inner wall.

[0120] A small portion of the light that continues to be reflected and oscillated inside the main structure 201 will be emitted into the fiber core of the second component 202. The portion of light that is not emitted into the fiber core of the second component 202 will continue to oscillate and reflect inside the main structure 201 until it is completely absorbed by the main structure 201 or the target emission source of the first component 204, or emitted into the fiber core of the second component 202.

[0121] Therefore, this optical oscillation cavity will greatly increase the coupling of light emitted by the target emission source of the first component 204 into the optical fiber core of the second component 202.

[0122] This greatly improves the coupling efficiency between the LED or laser diode target emission source and the optical fiber core of the second component 202 .

[0123] Through optical software simulation calculation, the following results can be obtained: Under the condition of the same target emission source and the same optical fiber core, and keeping the relative position relationship between the two unchanged. When the reflectivity of the inner wall of the main structure is 0.92, the coupling efficiency between the target emission source and the optical fiber core can be increased by about 11 times compared with the case where the present application is not applied; and when the reflectivity of the inner wall of the main structure is 0.98, the coupling efficiency can be increased by about 17 times. It can be seen that the present application significantly improves the coupling efficiency of the optical system.

[0124] When the target emission source is set to ultraviolet fiber or X-ray, the present application can be used for sterilizing and disinfecting gases or liquids. When the target emission source of the present application is set to a specific light that can perform photocatalysis, and in the oscillation cavity, the gas or liquid flows into and out of the channel through the liquid or gas, the present application can be used for the gas or liquid photocatalytic reaction in the chemical industry, which will greatly improve the reaction efficiency and yield. When the target emission source is set to infrared, the present application can be used to generate a very strong infrared radiation area inside the main structure, which can be used to quickly heat or high-temperature disinfect the gas or liquid passing therethrough. When the optical coupling principle model of the present application is adopted, it can be used to improve the coupling efficiency of LED or semiconductor lasers and optical fibers in optical communications, improve signal transmission distance, improve the signal-to-noise ratio in optical fibers, etc.

[0125] The above embodiments are only used to illustrate the technical solution of the present application but not to limit it. The present application is described in detail with reference to the preferred embodiments. It should be understood by those skilled in the art that the technical solution of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present application, and should be included in the scope of the claims of the present application.
