Description

Technical Field

[0001] This utility model relates to the field of optical communication technology, specifically to a dual-emitting optical device. Background Technology

[0002] Optical fiber communication has become one of the main communication methods due to its numerous advantages, such as large communication capacity, long transmission distance, and strong resistance to electromagnetic interference. The optical transmitter is the main light source used in optical fiber communication and is its core component. Currently, single-fiber transmitting optical devices are typically single-wavelength. When it is necessary to transmit optical signals of two wavelengths simultaneously, two separate optical devices are required, which is difficult to meet the increasingly diverse application needs and is also costly. Utility Model Content

[0003] In view of the technical problems in the prior art, the present invention provides a dual-emitting optical device, the purpose of which is to solve the above problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A dual-emitting optical device includes a housing having a accommodating chamber and a first coupling end, a second coupling end, and a third coupling end communicating with the accommodating chamber. The first and second coupling ends are arranged facing each other, and the third coupling end is perpendicular to the first and second coupling ends. The first and third coupling ends are respectively coupled to light emitters, and the second coupling end is coupled to a pigtail. A lens stage is provided in the middle of the accommodating chamber, which can guide the optical paths of the two light emitters to the pigtail. A transmission and reflection filter is also provided on the lens stage, and an adjustment structure is provided in the accommodating chamber corresponding to the transmission and reflection filter to adjust its angle.

[0006] Preferably, isolators are provided in the accommodating cavity at the locations of the two light emitters.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3This application proposes a dual-emission optical device according to this embodiment, including a housing 1. The housing 1 has a receiving chamber 2 for accommodating a light emitter 6 and other optical components. The housing 1 is provided with a first coupling end 3, a second coupling end 4, and a third coupling end 5, which are respectively connected to the receiving chamber 2. The first coupling end 3 and the second coupling end 4 are arranged opposite each other, and the third coupling end 5 is perpendicular to the first coupling end 3 and the second coupling end 4. The first coupling end 3 and the third coupling end 5 are respectively coupled to the light emitter 6 for emitting optical signals. The second coupling end 4 is coupled to a pigtail 7 for outputting optical signals.

[0020] A lens stage 8 is provided in the middle of the accommodating chamber 2. The function of the lens stage 8 is to guide the optical path of the two light emitters 6 to the pigtail 7. A transmittance and reflectance filter 9 is also provided on the lens stage 8 to control the reflection and transmission of the optical signal. The angle of the transmittance and reflectance filter 9 can be adjusted by the adjustment structure 10 to optimize the transmission efficiency of the optical signal. The adjustment structure 10 includes fixing blocks 12 at both ends of the transmittance and reflectance filter 9. The fixing block 12 at the upper end of the transmittance and reflectance filter 9 is hinged to the inner wall of the accommodating chamber 2, and the fixing block 12 at the lower end of the transmittance and reflectance filter 9 abuts against the inner bottom side of the accommodating chamber 2. The bottom of the housing 1 is provided with a top rod 13 that can slide longitudinally and can drive the fixing blocks 12 to rotate the transmittance and reflectance filter 9 along the hinge position of the upper fixing block 12 to adjust the angle. This design allows the angle of the transmittance and reflectance filter 9 to be finely adjusted as needed to adapt to different working environments and assembly requirements.

[0021] For ease of operation, an adjustment knob 14 is provided at the bottom of the housing 1 corresponding to the top rod 13. The adjustment knob 14 is rotatably connected to the housing 1, and the bottom of the top rod 13 is threadedly connected to the adjustment knob 14. By rotating the adjustment knob 14, the top rod 13 can be driven to slide longitudinally, thereby realizing the angle adjustment of the transmittance and reflection filter 9. The part of the top rod 13 located inside the housing 1 is provided with a limiting slider 15. A guide groove 16 is longitudinally opened inside the housing 1 corresponding to the limiting slider 15. The design of the limiting slider 15 and the guide groove 16 ensures the stability and accuracy of the top rod 13 during the sliding process, and avoids inaccurate adjustment caused by the tilting or offset of the top rod 13.

[0022] To further optimize the stability of the transmissive and reflective filter 9, grooves 17 are respectively provided on both sides of the bottom side wall of the accommodating chamber 2 corresponding to the top rod 13. A tension spring 18 is provided in the groove 17. One end of the tension spring 18 is fixedly connected to the bottom of the lower fixing block 12 of the transmissive and reflective filter 9, and the other end is fixedly connected to the bottom of the groove 17. The function of the tension spring 18 is to provide a certain elastic buffer when the top rod 13 drives the transmissive and reflective filter 9 to rotate, so as to ensure that the transmissive and reflective filter 9 remains stable during the adjustment process and can automatically return to the set angle after the adjustment is completed.

[0023] As described above, the dual-emission optical device of this invention can effectively achieve high-power light emission in both directions. Using an isosceles right-angled triangular prism lens stage 8, in conjunction with a transmittance / reflection filter 9, light emission in both horizontal and vertical directions can be achieved. The transmittance / reflection filter 9 can be adjusted in angle via the adjustment component 10. During assembly or under different operating environments (such as temperature changes, mechanical vibrations, etc.), the angle of the transmittance / reflection filter 9 can be fine-tuned to ensure that the light signal is reflected or transmitted at the optimal angle, thereby maximizing optical coupling efficiency. This optical device has a reasonable structure and strong practicality, making it particularly suitable for scenarios requiring high-power light emission and high-precision optical coupling.
