Abstract :
We developed a 22-Gbit/s × 16-ch WDM receiver based on a Si-Ge-silica monolithic photonic integration technology, in which a 16-ch SiOx AWG with 1.6-nm channel separation and Ge photodiodes are monolithically integrated. The AWG-PD device exhibited fiber-to-PD resoponsivity of 0.29 A/W and inter-channel crosstalk of less than 20 dB, and successfully received 22 Gbit/s signal for all 16 channels. In addition, we demonstrated 40-km transmission of 12.5 Gbit/s signal and obtained sensitivity of -6.8 dBm at BER of 10-9 without transimpedance amplifiers.
