Photonic integrated nanosecond 1×2 wavelength selective switch on 3-μm silicon platform

A 12-channel photonic integrated 1×2 electro-optic wavelength selective switch with nanosecond switching time is demonstrated on 3-μm silicon platform. Experimental results show 2.4ns switching time, 19.5dB average extinction-ratio, 7.8dB lowest insertion loss and error-free operation with <0.2dB power penalty at 10 Gb/s signal.
