Abstract
We present what is to our knowledge the first active-passive monolithically integrated 16×16 switch. The active InP/InGaAsP elements provide semiconductor optical amplifier gates in a multistage rearrangeably nonblocking switch design. Thirty-two representative connections, including the shortest, longest, and comprehensive range of intermediate paths have been assessed across the switch circuit. The 10 Gb/s signal routing is demonstrated with an optical signal-to-noise ratio up to 28.3 dB/0.1 nm and a signal extinction ratio exceeding 50 dB.
