Abstract :
We demonstrate a novel GaAs-metal-semiconductor-metal (MSM)-based wavelength-selective photodetector integrated with its complementary metal-oxide-semiconductor (CMOS) driver and receiver. This receiver has ∼1-ns wavelength switching access time and has been shown to detect 4 bits of 460-Mb/s (2.17-ns bit period) emulated data in nonreturn-to-zero format during the enabled 8.68-ns windows. The demonstrated channel spacing is ∼70.8 GHz. To our knowledge, this is the fastest reported wavelength switching time for a tunable optical receiver.
