4*4 InGaAlAs/lnAlAs MQW directional coupler waveguide switch modules integrated with spot-size converters and their 10 Gbit/s operation

摘要

4*4 InGaAlAs/InAlAs MQW directional coupler waveguide switch modules integrated with spot-size converters are developed for the first time. Because the switching time is sufficiently short (>70 ps, which is limited by the driver speed), no bits are lost during a 10 Gbit/s switching experiment at 1.55 mu m wavelength.
