Abstract: A hybrid integrated photodetector array receiving module with multiple optical chips is demonstrated, which can be used for a multi-channel high uniformity optical communication system. The receiving module includes a 100 GHz PLC type arrayed waveguide grating, a variable optical attenuator chip with 8-channel, a photodetector chip array, power regulation, an impedance matching circuit, etc. With the hybrid-integration technology and high-precision coupling process, the experimental results show that the coupling loss of the module is 3.40 dB. The crosstalk between the adjacent channels is -30 dB. And the adjustable range of the electric power is up to 20 dB.
