Abstract :
A novel, compact optical switch designed for use with integrated amplifiers to create more scalable photonic crossconnects is reported. The basic operation of the switch is described and experimentally verified. On/off ratios of 16.2 dB (7.5 dB) in the bar (cross) state are demonstrated with currents <30 mA and a very low bar state excess loss of 0.5 dB
