Abstract :
A side-illuminated waveguide integrated PIN photodiode (WG PIN PD) has been developed and modeled for use in 40 Gb/s PIN/preamp receiver module. The WG PIN PD exhibited a wide bandwidth over 40 GHz with a high responsivity. For the PIN/preamp modules with a GaAs pHEMT traveling wave amplifier (TWA), a clear eye-opening was observed and a recorded minimum received power of -11.2 dBm at 40 Gb/s was obtained for the first time.
