Abstract

Two types of waveguide photodiodes (WG-PD) - an evanescently coupled photodiode (EC-PD) and a separated-absorption-and-multiplication avalanche photodiode (SAM-APD) - have been developed for use in 40-Gbps receivers. The EC-PD simultaneously exhibited high external responsivity of 0.96 A/W and wide bandwidth of >40 GHz. The SAM-APD showed wide bandwidth of 30-35 GHz and gain-bandwidth (GB) product of 140-180 GHz. High receiver sensitivities of -11.3 dBm at 43 Gbps and -19 dBm at 40 Gbps have been successfully achieved for the EC-PD and the SAM-APD, respectively.
