In this paper,a 12-channel parallel optical receiver module with each channel’s data rate up to 3.318 Gbit/s is designed and fabricated.An 850 nm GaAs photodetector(PD) array is adopted as the receiver device,and the PD chip is directly wire bonded to a 12-channel high speed IC.The inputs of the PD array are directly coupled into a 12-channel fiber array.We developed a new technology using jointing machine to couple the PD array with fiber array without power supply.The efficiency is 80% and the...
