Description

Technical Field

[0001] This application relates to an isolator based on magneto-optical waveguide and its usage method, belonging to the field of integrated optoelectronic device technology. Background Technology

[0002] Optical waveguides are fundamental components of integrated optics. They are defined as a region of high-refractive-index medium surrounded on both sides by a low-refractive-index medium. Optical waveguides confine light within their boundaries, thus increasing transmission efficiency and reducing light source power. Ion implantation technology can alter the physical properties of solid surfaces and has been successfully used to form planar optical waveguides on various bulk materials. Compared to other waveguide fabrication methods (such as diffusion, ion exchange, and surface epitaxial growth), ion implantation offers unique advantages: it can be performed at room temperature or low temperature, the implanted energy and dosage can be precisely controlled, and a wide variety of implanted ions can be used. Currently, a combination of ion implantation and femtosecond laser ablation is commonly used to fabricate ridge waveguide structures. Femtosecond laser ablation, due to its high electric field intensity in the focal region, exhibits high peak power and power density, allowing for rapid ablation of specific areas. Ridge waveguides can be fabricated using femtosecond laser ablation on planar waveguides. In addition, femtosecond laser processing technology is also a novel microstructure processing technology. It is used to inscribe gratings and fabricate integrated optical circuits on materials such as solids and glass. However, isolators based on magneto-optical waveguides are susceptible to damage from external devices during non-operating periods. Summary of the Invention

[0031] The present application is described in detail below with reference to the embodiments, but the present application is not limited to these embodiments.

[0032] Unless otherwise specified, all raw materials used in the embodiments of this application were purchased through commercial channels.

[0033] In one embodiment, the structure of the isolator based on the magneto-optical waveguide is as follows: Figure 1 and Figure 2As shown, the device includes an upper baffle 1. Connecting columns 2 are fixedly connected to the left and right edges of the upper surface of the upper baffle 1. An upper column 3 is welded to the upper end of the connecting column 2. A lower column 4 is provided at the lower end of the upper column 3. A telescopic column 12 is provided through the inner upper surface of the lower column 4. A telescopic rod 19 is provided at the center of the upper surface of the telescopic column 12. A fixing block 18 is fixedly connected to the upper surface of the telescopic rod 19. A rotating shaft 15 is fixedly connected to the center of the left and right surfaces of the fixing block 18. An outer ring 14 is rotatably provided on the outer surface of the rotating shaft 15. A rotating block 17 is welded to the outer circumferential surface of the outer ring 14. A motor 13 is fixedly connected to the outer surface of the outer ring 14. The upper surface of the rotating block 17 is welded with an upper connecting column 16. A protective device is installed on the upper surface of the isolator body. The protective device mainly consists of an upper baffle, an upper column, and other structures. When the isolator is in use, under the action of the motor and telescopic column inside the lower column, the upper baffle will move upward and leave the surface of the isolator body. The internal motor will then open the upper baffle to the outside, exposing the upper surface of the isolator body for operation. At the same time, when the isolator is not in use, the upper baffle can be covered on its surface to protect the body from damage by external equipment, thus improving the overall safety of the equipment.

[0034] like Figure 3 As shown, an upper connecting column groove 20 is provided on the lower end surface of the upper column 3. The purpose of providing an upper connecting column groove on the lower surface of the upper column is to connect the upper column and the lower column separately. By separating the structure, the two parts can be treated differently, which can achieve a more convenient effect when the equipment needs to be replaced.

[0035] like Figure 1 As shown, an upper guide layer 11 is provided on the lower surface of the upper baffle 1, and a middle guide layer 10 is installed on the lower surface of the upper guide layer 11. A large guide hole 5 is opened on the upper surface of the middle guide layer 10, and a small guide hole 6 is opened on the lower surface of the middle guide layer 10. The purpose of opening large and small guide holes on the upper and lower surfaces of the middle guide layer is to guide out light waves of different frequencies to achieve a better isolation effect.

[0036] like Figure 1 As shown, a lower guide layer 7 is installed on the lower surface of the middle guide layer 10, and a substrate 8 is provided on the lower surface of the lower guide layer 7. Installing the substrate on the lower surface of the lower guide layer facilitates the installation of the overall device. At the same time, two guide layers are provided to improve the isolation effect of the device.

[0037] like Figure 4As shown, a light glass 25 is disposed through the interior of the substrate 8. Fixing protrusions 24 are fixedly installed on the left and right edges of the upper surface of the substrate 8. A front fixing plate 23 is welded to the front surface of the fixing protrusions 24. A fixing plate opening 22 is provided through the upper section of the front fixing plate 23. The substrate is disposed on the lower surface of the isolator body, and screw holes are opened at the front and back of the upper surface of the substrate for fixing the whole device to other devices. The substrate is installed to the isolator body through the protrusions to prevent the isolator body from detaching from the substrate, so as to achieve a more stable fixation.

[0038] like Figure 1 As shown, fixing holes 9 are provided through the front and rear ends of the upper surface of the substrate 8. Screws are used to connect the entire device to other devices, which eliminates the problem of the device not being securely installed and improves the reliability of the device during use.

[0039] like Figure 5 As shown, a central scattering ring 26 is provided at the center of the upper surface of the lower guide layer 7, and an outer scattering ring 27 is provided at the position outside the central scattering ring 26 on the upper surface of the lower guide layer 7. The central scattering ring and the outer scattering ring are respectively provided on the upper surface of the lower guide layer, which can further export the residual magneto-optical wave and significantly improve the effect of the device in isolating magneto-optical waves.

[0040] like Figure 6 As shown, a protruding plate groove 28 is provided on the lower surface of the lower guide layer 7 relative to the fixed protruding plate 24. The protruding plate groove is provided at the edge of the lower surface of the lower guide layer. At the same time, the protruding plate is set to a structure that is larger at the top and smaller at the bottom, which can improve the stability of the installation.

[0041] like Figure 3 As shown, a fixed suction cup 21 is provided on the lower surface of the connecting column 2. The connecting column is connected to the upper baffle through the suction cup. The purpose is to facilitate the operator to replace the upper baffle of different materials to achieve a better protection effect.

[0042] In one implementation, such as Figure 1-6 The illustrated method of using the magneto-optical waveguide-based isolator includes:

[0043] Step 1: After installing the substrate 8 on other equipment, fix it through the fixing holes 9 opened at both ends of the upper surface of the substrate 8, and fix the isolator through the fixing protrusions 24 installed at the left and right edges of the upper surface of the substrate 8, which are installed inside the protrusion grooves 28 opened on the lower surface of the lower guide layer 7.

[0044] Step 2: When using the isolator, the telescopic column 12 installed inside the lower column 4 is activated to separate the upper column 3 from the lower column 4. At the same time, the upper baffle 1 connected to the connecting column 2 moves longitudinally away from the isolator body and opens outward under the action of the motor 13, so that the isolator body can work.

[0045] Step 3: The magneto-optical wave is extracted through the large via 5 and the small via 6 inside the isolator. Then, under the action of the central scattering ring 26 and the external scattering ring 27 opened on the upper surface of the substrate 8, the magneto-optical wave is extracted to a greater extent, thus achieving the isolation effect.

[0046] The implementation principle of the isolator based on magneto-optical waveguide and its usage method in this application is as follows: A protective device is set on the upper surface of the isolator body. The protective device mainly consists of an upper baffle, an upper column, and other structures. When the isolator is in use, under the action of the motor and telescopic column inside the lower column, the upper baffle moves upward and away from the surface of the isolator body. The upper baffle is then opened to the outside by the internal motor, exposing the upper surface of the isolator body for operation. At the same time, when the isolator is not in use, the upper baffle can be covered on its surface to protect the body from damage by external equipment, thereby improving the overall safety of the equipment.

[0047] The above description is merely a few embodiments of this application and is not intended to limit this application in any way. Although this application discloses preferred embodiments as described above, it is not intended to limit this application. Any changes or modifications made by those skilled in the art without departing from the scope of the technical solution of this application using the disclosed technical content are equivalent to equivalent implementation cases and fall within the scope of the technical solution.
