Ultra-broadband, low-power, 2×2 electro-optic switch using sub-micron silicon waveguides

We present a broadband Mach-Zehnder electro-optic switch capable of simultaneously routing multiple channels within 110-nm optical bandwidth with only 3.1-mW power consumption and a 4-ns switching time. Switching bandwidth is maintained over 30°C temperature variation. © 2010 Optical Society of America.
