摘要:

We demonstrate a monolithically integrated waveguide polarization diversity photodector on InP with total length below 210 &mgr;m. High quantum efficiency (87% TE) and extinction ratios of 10.6 dB (TE) and 16 dB (TM) are achieved at 1.5 &mgr;m wavelength with simple fabrication processes. The device employs extremely short (21 and 31 &mgr;m) waveguide photodiodes that are suitable for high bandwidth operation.
