Dynamic response of 2 × 2 InGaAlAs/InAlAsmultiquantum well (MQW) directionalcoupler waveguide switch modules

Abstract
The first dynamic response of fully packaged 2 × 2 InGaAlAs/InAlAs MQW directional coupler waveguides with spotsize converters is reported. The switching time is sufficiently fast at 100 ps. Only 1 bit of the 10 Gbit/s signal is lost during switching.
