Description

Technical Field

[0001] The present application relates to the technical field of optical isolators, and in particular to a bidirectional conductive device of an optical isolator and an optical isolator. Background Art

[0002] An optical isolator is a passive optical device that only allows light to pass in one direction. Its working principle is based on the non-reciprocity of Faraday rotation, which allows light to pass in one direction and cut off in the opposite direction, that is, light can only be transmitted in one direction. Generally speaking, an optical isolator adjusts the light through an internal optical rotator to change the light to the required angle. The rotation adjustment of the optical rotator of an existing optical isolator is generally performed during the production and assembly process. After the optical rotator is adjusted to the required angle, it is packaged with glue. After the package is sealed, the optical rotator crystal cannot be adjusted anymore.

DETAILED DESCRIPTION

[0050] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0051] Please refer to the attached Figure 1-2 One embodiment of the present application provides a bidirectional conduction device of an optical isolator, comprising:

[0052] A first rotating member 10, on which a plurality of first adjusting members 11 are arranged around a center;

[0053] A second rotating member 20, on which a plurality of second adjusting members 21 are arranged around a center;

[0054] The distance from the center of the first adjusting member 11 to the center of the first rotating member 10 is equal to the distance from the center of the second adjusting member 21 to the center of the second rotating member 20;

[0055] The first rotating member 10 and the second rotating member 20 rotate around the same axis or axes parallel to each other, so that the first adjusting member 11 gradually overlaps with the corresponding second adjusting member 21 until they are located on the same axis;

[0056] In the process that the first adjusting member 11 and the corresponding second adjusting member 21 gradually overlap until they are located on the same axis; the light entering the first adjusting member 11 is adjusted by the second adjusting member 21 to be the target light that can pass through the second adjusting member 21; or, the light entering the second adjusting member 21 is adjusted by the first adjusting member 11 to be the target light that can pass through the first adjusting member 11; or, the light passes directly from the first adjusting member 11 and the second adjusting member 21.

[0057] In the present application, the first rotating member 10 is used to install the first adjusting member 11, and the second rotating member 20 is used to install the second rotating member 20. Multiple first adjusting members 11 cooperate with corresponding multiple second adjusting members 21. The corresponding light conduction effect is achieved by controlling the alignment of different first adjusting members 11 with different second adjusting members 21. The user can control the rotation of the first rotating member 10 and the second rotating member 20 according to actual needs to select the required light conduction effect.

[0058] In the present application, it should be noted that the present application does not limit the shapes of the first rotating member 10 and the second rotating member 20, that is, the first rotating member 10 and the second rotating member 20 can be round, square or even diamond-shaped, etc. It is only necessary to ensure that the distance from the center of the first adjusting member 11 to the center of the first rotating member 10 is equal to the distance from the center of the second adjusting member 21 to the center of the second rotating member 20. The purpose of this setting is to ensure that when the first rotating member 10 and the second rotating member 20 are rotated, the corresponding first adjusting member 11 and the second adjusting member 21 can be aligned, that is, gradually overlap until they are located on the same axis to ensure that light can pass through. In the present application, please refer to the attached Figure 1 The first rotating member 10 and the second rotating member 20 can be rotated around the same axis to ensure that the first adjusting member 11 and the second adjusting member 21 can gradually overlap (their projections) during the rotation process. Figure 2 , rotating the first rotating member 10 and the second rotating member 20 around axes parallel to each other, it is only necessary to make the distance from the center of the first adjusting member 11 to the center of the first rotating member 10 equal to the distance from the center of the second adjusting member 21 to the center of the second rotating member 20, and it is also possible to achieve that the first adjusting member 11 and the second adjusting member 21 (their projections) gradually overlap during the rotation process.

[0059] It should also be noted that the above-mentioned gradual overlap until they are located on the same axis means that in the present application, when the first adjustment member 11 and the second adjustment member 21 have overlapping parts, the corresponding light conduction effect can be achieved, rather than completely overlapping to be located on the same axis to achieve the corresponding light conduction effect.

[0060] In addition, in the present application, the first rotating member 10 can be fixed and the second rotating member 20 can be rotated to achieve the desired effect, or the second rotating member 20 can be fixed and the first rotating member 10 can be rotated to achieve the desired effect, or both the first rotating member 10 and the second rotating member 20 can be rotated to achieve the desired effect.

[0061] The following embodiments will provide a detailed introduction and description of the different light conduction effects that can be achieved in this application.

[0062] First, see the attached Figure 8-12 , the structures of the first adjusting member 11 and the second adjusting member 21 of another embodiment of the present application are described in detail, the first adjusting member 11 and the second adjusting member 21 are both through-holes 30; or, the first adjusting member 11 is a first polarizer 40 arranged in the through-hole 30, and the second adjusting member 21 is an optically active crystal 50 and a second polarizer 60 arranged in sequence in the through-hole 30; or, the first adjusting member 11 is a first polarizer 40 and an optically active crystal 50 arranged in sequence in the through-hole 30, and the second adjusting member 21 is a second polarizer 60 arranged in the through-hole 30.

[0063] In this embodiment, when the first adjusting member 11 and the second adjusting member 21 are both perforations 30, the light passing through is not changed, that is, the light directly passes through the two perforations 30, and the conduction effect of the light passing directly is achieved. When the first adjusting member 11 and the second adjusting member 21 are the two cases described later, corresponding adjustments can be made according to actual needs. Among them, a first polarizer 40 and a second polarizer 60 with multiple different deflection angles, and a plurality of optically active crystals 50 with different rotation angles are included to achieve the bidirectional conduction effect of the light, and the specific situation will be described in the following embodiments.

[0064] Secondly, please see the attached Figure 3-7 , the bidirectional conductive device in this application also includes:

[0065] A first baffle plate 70, wherein a first through slot 71 is formed on the first baffle plate 70;

[0066] A second baffle plate 80, wherein a second through slot 81 is formed on the second baffle plate 80, and the second through slot 81 and the first through slot 71 are located on the same axis;

[0067] The first baffle 70 is disposed at one side of the first rotating member 10 , and the second baffle 80 is disposed at one side of the second rotating member 20 .

[0068] The first baffle plate 70 and the second baffle plate 80 are used to install the first through slot 71 and the second through slot 81 respectively. The first through slot 71 is used to allow light to enter the two-way conductive device from a specific position, and the second through slot 81 is used to allow light to be guided out of the two-way conductive device from a specific position. Specifically, the two are arranged on the same axis, and can cooperate with the corresponding first adjustment member 11 and the second adjustment member 21, that is, when the first adjustment member 11 and the second adjustment member 21 are rotated to overlap with the first through slot 71 and the second through slot 81, the corresponding light conduction effect is achieved. This arrangement ensures that only one group of the first adjustment member 11 and the second adjustment member 21 is aligned to achieve the conduction effect, and the remaining first adjustment members 11 and the second adjustment members 21 are blocked by the non-through slot parts of the first baffle plate 70 and the second baffle plate 80 even if they are aligned, and cannot conduct light, thereby ensuring the single-channel conduction effect of the two-way conductive device, reducing interference, and ensuring accuracy.

[0069] The following describes the conduction effect of different light rays by taking an embodiment as an example: taking the passage formed by the first through slot 71 of the first baffle 70 and the second through slot 81 of the second baffle 80 as an example, a plurality of first adjusting members 11 are provided on the first rotating member 10, and a plurality of second adjusting members 21 are provided on the second rotating member 20. The first adjusting member 11 includes a through hole 30, a first polarizing plate 40, and the first polarizing plate 40 and the optically active crystal 50 arranged in sequence; the second adjusting member 21 includes a through hole 30, an optically active crystal 50 and a second polarizing plate 60 arranged in sequence, and a second polarizing plate 60.

[0070] The invention comprises a first polarizer 40 and a second polarizer 60 with at least two polarization angles perpendicular to each other, and an optical rotatory crystal 50 with at least two rotation angles perpendicular to each other.

[0071] The user rotates the first rotating member 10 and the second rotating member 20 during use, selects the required first adjusting member 11 and the corresponding second adjusting member 21 according to actual needs, and aligns them to the formed passage through rotation. The alignment of each first adjusting member 11 and each second adjusting member 21 is shown in the attached figure. Figure 8-12 (The arrows in the figure indicate the direction of light that can pass through), including:

[0072] (1) Please refer to Figure 8 As shown in (A1), when the through hole 30 of the first adjusting member 11 and the through hole 30 of the second adjusting member 21 are gradually aligned with the passage, no matter which end the light enters from, it can be unobstructedly guided out from the other end through the first adjusting member 11 and the second adjusting member 21. In this case, the light is unobstructedly conducted in both directions, and the conduction amount of the light reaches the maximum.

[0073] (2) Please refer to Fig. 9 As shown in (B1) and (B2), when the first polarizer 40 of the first adjusting member 11, the optical rotatory crystal 50 and the second polarizer 60 of the second adjusting member 21 are aligned with the passage, or the first polarizer 40 and the optical rotatory crystal 50 of the first adjusting member 11, and the second polarizer 60 of the second adjusting member 21 are aligned with the passage; and at this time, the aligned first polarizer 40, the optical rotatory crystal 50 and the second polarizer 60 are changed by 45° in sequence.

[0074] In this case, the light passing through the first through slot 71 passes through the first adjusting member 11 and the second adjusting member 21 in sequence, and is finally guided out of the second through slot 81. In this process, the light entering the first adjusting member 11 is adjusted by the second adjusting member 21 to be the target light that can pass through the second adjusting member 21, while on the contrary, the light entering from the second through slot 81 cannot reach the first through slot 71, thereby achieving the unidirectional conduction effect of the optical isolator.

[0075] An example is used to illustrate (2). In this example, the polarization angle of the first polarizer 40 is 90°, the rotation angle of the optical rotator crystal 50 is 45°, and the polarization angle of the second polarizer 60 is 45°. At this time, the light passing through the first polarizer 40 is deflected to 90°, rotated to 45° by the optical rotator crystal 50, and then output from the second polarizer 60, while the light passing through the second polarizer 60 is deflected to 45°, and after being rotated by the optical rotator crystal 50, it becomes 0° and cannot pass through the first polarizer 40, thereby achieving a unidirectional light conduction effect.

[0076] After (2) is completed, it is necessary to achieve a two-way conduction effect of light, which can be achieved through three switching methods. Please refer to the following (3), (4), and (5) for the situations described.

[0077] (3) Please refer to Fig.10 As shown in (C1) and (C2) in the figure, the first polarizer 40 capable of achieving reverse conduction is adjusted to obtain the corresponding first polarizer 40: that is, the first rotating member 10 is continued to be rotated, and another first adjusting member 11 is aligned with the original second adjusting member 21. The first adjusting member 11 is the first polarizer 40, or is the first polarizer 40 and the optical rotation crystal 50 arranged in sequence. The polarization angles of the first polarizer 40 and the original first polarizer 40 (i.e., the first polarizer 40 in (2)) are perpendicular to each other, thereby achieving the reverse conduction function of the light after (2).

[0078] An example is used to illustrate (3). In this example, the setting parameters in (2) are as follows: the polarization angle of the first polarizer 40 is 90°, the rotation angle of the optical rotator crystal 50 is 45°, and the polarization angle of the second polarizer 60 is 45°. At this time, as shown in the above example, the unidirectional conduction function of light is realized. On this basis, the rotation adjustment in (3) is performed, and the first polarizer 40 after adjustment is 0°, so that the light that becomes 0° after the rotation of the optical rotator crystal 50 can pass through the first polarizer 40, thereby realizing the bidirectional conduction effect of light. The above example is a combined implementation example of (2) and (3). The user can perform corresponding rotation according to actual needs and actual parameter settings to align the required first adjustment member 11 and the second adjustment member 21, thereby realizing the required bidirectional conduction effect of light.

[0079] (4) Please refer to Fig.11 As shown in (D1) and (D2) in the figure, the adjustment is made to obtain the corresponding second polarizer 60 capable of realizing reverse conduction: that is, the second rotating member 20 is continued to be rotated, and another second adjusting member 21 is aligned with the original first adjusting member 11. The second adjusting member 21 is the second polarizer 60, or is the optical rotation crystal 50 and the second polarizer 60 arranged in sequence. The polarization angles of the second polarizer 60 and the original second polarizer 60 (i.e., the second polarizer 60 in (2)) are perpendicular to each other, thereby realizing the reverse conduction function of the light after (2).

[0080] An example is used to illustrate (4). In this example, the setting parameters in (2) are as follows: the polarization angle of the first polarizer 40 is 90°, the rotation angle of the optical rotator crystal 50 is 45°, and the polarization angle of the second polarizer 60 is 45°. At this time, as shown in the above example, the unidirectional conduction function of light is realized. On this basis, the rotation adjustment in (4) is performed, and the adjusted second polarizer 60 is -45°, so that the light passing through the second polarizer 60 is deflected to -45°. The deflected light enters the optical rotator crystal 50, and is rotated to -90° (opposite to 90° but parallel) by the optical rotator crystal 50, so that it can be guided out from the first polarizer 40, thereby realizing the bidirectional conduction effect of light. The above example is a combined implementation example of (2) and (4). The user can perform corresponding rotation according to actual needs and actual parameter settings to align the required first adjustment member 11 and the second adjustment member 21, thereby realizing the required bidirectional conduction effect of light.

[0081] (5) Please refer to Fig.12As shown in (E1) and (E2) in (2), the adjustment is made to obtain the corresponding optically active crystal 50 capable of achieving reverse conduction: that is, the first rotating member 10 or the second rotating member 20 is continued to rotate, and another first adjusting member 11 is aligned with the original second adjusting member 21, or another second adjusting member 21 is aligned with the original first adjusting member 11. The first adjusting member 11 is a first polarizer 40, or a first polarizer 40 and an optically active crystal 50 are arranged in sequence. The second adjusting member 21 is a second polarizer 60, or an optically active crystal 50 and a second polarizer 60 are arranged in sequence. The rotation angle of the optically active crystal 50 is perpendicular to the rotation angle of the original optically active crystal 50 (i.e., the optically active crystal 50 in (2)), thereby achieving the reverse conduction function of the light after (2).

[0082] An example is used to illustrate (5). In this example, the setting parameters in (2) are as follows: the polarization angle of the first polarizer 40 is 90°, the rotation angle of the optical rotator crystal 50 is 45°, and the polarization angle of the second polarizer 60 is 45°. At this time, as shown in the above example, the unidirectional conduction function of light is realized. On this basis, the rotation adjustment in (5) is performed, and the adjusted optical rotator crystal 50 is rotated at an angle of -45°, so that the light deflected to 45° by the second polarizer 60 is rotated to 90° by the optical rotator crystal 50 after entering the optical rotator crystal 50, so that it can be guided out of the first polarizer 40, thereby realizing the bidirectional conduction effect of light. The above example is a combined implementation example of (2) and (5). The user can perform corresponding rotation according to actual needs and actual parameter settings to align the required first adjustment member 11 and the second adjustment member 21, thereby realizing the required bidirectional conduction effect of light.

[0083] From the description of the above examples, it can be known that the present application can adjust the corresponding first polarizer 40, optical rotatory crystal 50 or second polarizer 60 by rotating the first rotating member 10 and the second rotating member 20 to achieve reverse conduction of light, and then achieve bidirectional conduction of light. In actual work, it can adapt to different installation situations. For example, when the corresponding optical isolator is installed in the opposite direction, there is no need to remove and reinstall it, only need to make corresponding adjustments so that the light can be reversely conducted. In the present application, it should be noted that the first polarizer 40, optical rotatory crystal 50 and second polarizer 60 in the present application can be respectively arranged on different rotating members according to actual needs, such as respectively arranged on different rotating members (in this case, three rotating members are required), or they can be respectively arranged on two rotating members as shown in the above embodiment to reduce consumables, but not all are arranged on one rotating member. In this case, the function that can be achieved by rotation is lost, and only one-way conduction can be achieved.

[0084] In one embodiment, as shown in the attached Figure 13-14As shown, the first rotating member 10 or the second rotating member 20 is arranged on the fixing mechanism 90; the fixing mechanism 90 includes a first central axis 91, a central axis fixing plate 92 and a first fixing plate 93; the first central axis 91 is arranged through the center of the first rotating member 10 or the second rotating member 20, and both ends of the first central axis 91 are rotatably arranged on the central axis fixing plate 92, and the central axis fixing plate 92 is arranged on the first fixing plate 93; the first central axis 91 is connected to the rotating mechanism 100.

[0085] In this embodiment, the first central axis 91 is used to fix the first rotating member 10 or the second rotating member 20, the central axis fixing plate 92 is used to install the first central axis 91, and the first fixing plate 93 is used to install the central axis fixing plate 92. Under this fixing mechanism 90, the first rotating member 10 or the second rotating member 20 is driven to rotate through different rotating mechanisms 100.

[0086] In one embodiment, as shown in the attached Figure 13-14 As shown, the rotating mechanism 100 includes a driven gear 101, a chain 102, a driving gear 103 and a driving motor 104; the driven gear 101 is fixedly arranged at one end of the first central axis 91, and the driven gear 101 is located on one side of the central axis fixing plate 92. The driven gear 101 is connected to the driving gear 103 through the chain 102, and the driving gear 103 is connected to the driving motor 104, and the driving motor 104 is arranged on the first fixing plate 93.

[0087] In this embodiment, the driving gear 103 and the driven gear 101 are respectively meshed with the chain 102, and the driving motor 104 controls the driving gear 103 to rotate. The driving gear 103 rotates to drive the chain 102 to move, and the chain 102 drives the driven gear 101 to rotate, thereby driving the first rotating member 10 or the second rotating member 20 to rotate.

[0088] In one embodiment, as shown in the attached Figure 15-16 As shown, the rotating mechanism 100 includes a magnet 105, a coil assembly 106 and a coil fixing plate 107; the magnet 105 is arranged at one end of the first central axis 91, the coil assembly 106 is arranged outside the magnet 105, and the coil assembly 106 is arranged on the first fixing plate 93 through the coil fixing plate 107; the coil assembly 106 is connected to a power supply, and the coil assembly 106 drives the magnet 105 to drive the first central axis 91 to rotate by energizing.

[0089] In this embodiment, the coil assembly 106 is energized by a power source, and the driving magnet 105 drives the first central shaft 91 to rotate, thereby driving the first rotating member 10 or the second rotating member 20 to rotate.

[0090] In one embodiment, as shown in the attached Fig.17As shown, the bidirectional conductive device also includes a coaxial component 200, which includes a second central axis 201, a first rotating flange 202 and a second rotating flange 203; one end of the second central axis 201 is connected to the first central axis 91 of the first rotating member 10 through the first rotating flange 202, and the other end of the second central axis 201 is connected to the first central axis 91 of the second rotating member 20 through the second rotating flange 203.

[0091] In this embodiment, the coaxial assembly 200 is configured to ensure the coaxiality of the first rotating member 10 and the second rotating member 20 when they rotate around the same axis. The first central axis 91 of the first rotating member 10 rotates about the axis of the second central axis 201 through the first rotating flange 202, and the first central axis 91 of the second rotating member 20 rotates about the axis of the second central axis 201 through the second rotating flange 203. At this time, the first rotating flange 202 and the second rotating flange 203 both rotate relative to the second central axis 201, and the second central axis 201 is stationary.

[0092] In one embodiment, as shown in the attached Figure 18-19 As shown, a heat dissipation channel 300 is provided inside the first rotating member 10 or the second rotating member 20, and heat conduction oil is provided in the heat dissipation channel 300. The heat dissipation channel 300 includes:

[0093] Heat absorbing pipe 301: arranged around the first adjusting member 11 or the second adjusting member 21;

[0094] Heat dissipation pipe 302: arranged around the outer surface of the first rotating member 10 or the second rotating member 20;

[0095] The heat absorbing pipe 301 is connected to a first channel 303 and a second channel 304 , and the first channel 303 and the second channel 304 are connected to the heat dissipating pipe 302 respectively.

[0096] In this embodiment, the heat dissipation channel 300 is used to reduce the heat in the first adjustment member 11 or the second adjustment member 21, and the heat is absorbed by the heat transfer oil inside the channel to ensure the stability of the operation. Among them, the heat absorption pipe 301 is used to absorb the heat in the first adjustment member 11 or the second adjustment member 21. Due to the uneven heat, the temperature of the channel near the first adjustment member 11 or the second adjustment member 21 is higher than the temperature near the outer surface of the first rotating member 10 or the second rotating member 20, so that the heat transfer oil in the heat absorption channel absorbs the heat and moves through the first channel 303 or the second channel 304 at one end into the heat dissipation pipe 302 on the surface, and gradually reduces the heat by circulating in the heat dissipation pipe 302. After circulating in the heat dissipation pipe 302 for one circle, the heat transfer oil returns to the heat absorption pipe 301 through the first channel 303 or the second channel 304 at the other end, and the cycle is repeated to take away the heat in the first adjustment member 11 or the second adjustment member 21.

[0097] In another embodiment, as shown in the attached Figure 20-21 As shown, the first channel 303 and the second channel 304 are arranged perpendicular to the central axis of the first rotating member 10 or the second rotating member 20. The purpose of this arrangement is to make the best use of the influence of gravity on the heat transfer oil, combined with the influence of temperature difference, to ensure the circulation of the heat transfer oil from the heat absorption pipe 301 to the heat dissipation pipe 302 and then back to the heat absorption pipe 301.
