Background technique

With the development of optical transmission research, wavelength division multiplexing technology has become an effective means to increase the capacity of communication information. Wavelength division multiplexing refers to the transmission of multiple wavelengths, which are coupled to the same waveguide or optical fiber of an optical line. Demultiplexing refers to the technique of separating the total light in a waveguide or an optical fiber by wavelength. The arrayed waveguide grating is realized. An ideal device for wavelength division multiplexing/demultiplexing, which can be coupled with an optical channel of an optoelectronic transceiver array to realize mutual conversion of optical signals and electrical signals. At present, the optical path angle method is often used to realize the vertical coupling between the arrayed waveguide grating and the photoelectric transceiver array. Generally, the optical fiber array is ground into a 45° mirror to realize a 90° rotation angle of the optical signal. The use of this method to achieve the optical path angle in practical applications shows the following problems:

1. When grinding the optical fiber array, it is necessary to destroy the output end surface of the arrayed waveguide grating chip or the output end surface of the optical fiber array. When the optical fiber is ground, the optical fiber is easily broken, which is not easy to be mass-produced, and the yield is low. After grinding, the lower end of the ground surface of the fiber is very fragile, and it is easily broken and cannot be used in the subsequent process.

2. When the fiber is ground, the fiber may be bent or twisted, which affects the accuracy of the grinding angle, thereby affecting the reflection precision of the fiber array, and thus the coupling efficiency between the arrayed waveguide grating and the photoelectric transceiver array is low.

3. When the arrayed waveguide grating is coupled with the optoelectronic transceiver array, the reflective area of the fiber cannot be The use of shadowless glue for seamless matching results in the transmission of optical signals in the air, thereby diverging the spot, further resulting in lower coupling efficiency between the arrayed waveguide grating and the optoelectronic transceiver array.
