A Nonblocking 4×4 Mach-Zehnder Switch with Integrated Gain and Nanosecond-Scale Reconfiguration Time

We present a silicon photonic switch assembly integrating a nonblocking 4×4 Mach-Zehnder switch and a flip-chipped SOA array. The switch provides close to net-neutral-loss in the full C-band for all states and shows nanosecond-scale reconfiguration time.
