Abstract
We report the fabrication and characterization of the two-bit monolithic optical time-delay network on GaAs. GaAs rib-waveguides and InGaAs waveguide-coupled MSM detectors serve respectively as delay-lines and optoelectronic switches on the photonic integrated circuit. From the linear RF differential phase observed between 1 and 11 GHz, we estimate that the measured time-delays are within 4 psec of their designed values.Keywords
