Design of optoelectronic couple module and analysis of couple efficiency

In order to improve the Couple efficiency of optoelectronic transmission, an efficient optocoupler is designed. A simulation model of the optoelectronic Couple system is established using Zemax software, and the structure of the optoelectronic Couple system is optimized using the orthogonal descent method. The optical signal emitted by the vertical cavity surface laser with a wavelength of 850nm is coupled into the fiber, and the Couple efficiency of the optoelectronic Couple system is simulated and analyzed. The Couple efficiency is fitted using Origin software Curve diagram between Couple loss and alignment offset. The design and simulation results show that the maximum Couple efficiency of optoelectronic transmission is 92.71%, and the maximum loss generated by optoelectronic Couple is 0.7dB. According to the high-precision assembly requirements of optoelectronic devices, the photoelectric transmission efficiency has not been significantly affected.
