[0038] Preferably, the optical signal receiving device 11 includes: a ceramic ferrule 18, a chip holder 19, an optical fiber filter 20, a photosensitive chip 21, a positive electrode chip pin 22, and a negative electrode chip pin 23. The ceramic ferrule 18 has a U-shaped mounting groove 24 in the middle and optical fiber pre-embedded holes 25 extending axially at both ends and communicating with the U-shaped mounting groove 24. The chip holder 19 is installed in the U-shaped mounting groove 24 and includes a lower holder 26 and an upper holder 27 connected to the upper end of the lower holder 26. The lower holder 26 has a filter mounting groove 28 and an optical fiber positioning groove 29 at its bottom, and the upper holder 27 has a chip mounting groove 30 at its bottom. The filter mounting groove 28 has a light-transmitting hole 46 communicating with the chip mounting groove 30. The light-transmitting hole 46 is located at the center of the filter mounting groove 28 and has a length of 0.4mm-0.45mm and a width of 0.1mm-0.15mm. Ideally, the light-transmitting hole 46 has a size of 0.4mm * 0.15mm.

The diffraction grating is an optical element with a periodic structure, which periodically modulates the amplitude or phase (or both) of the incident light through a regular structure. The main function of the diffraction grating is to split and diffract the incident light into multiple beams propagating in different directions. The fiber optic filter is also a key optical element, widely used in optical communication systems. Its main function is to filter out optical signals of specific wavelengths, allowing only the required wavelengths to pass through, thereby ensuring the quality and efficiency of optical signal transmission. Both the diffraction grating and the fiber optic filter are known technologies.
