Abstract
We report the first experimental demonstration of a monolithically integrated hybrid dilated modular optical switch using Mach–Zehnder modulators as low-loss switching elements and short semiconductor optical amplifiers to provide additional extinction and gain. An excellent 40 dB cross-talk/extinction ratio is recorded with data-modulated signal-to-noise ratios of up to 44 dB in a 0.1 nm bandwidth. A switching time of 3 ns is demonstrated. Bit error rate studies show extremely low subsystem penalties of less than 0.1 dB, and studies indicate that, by using this hybrid switch building block, an port switch could be achieved with 14 dB input power dynamic range for subsystem penalties of less than 0.5 dB.
