In this paper we demonstrate InGaAsP-InP MQW 2*2 optical space switches that show excellent dc switching performance and are capable of operation at and beyond 10 GHz. Both 2*2 Mach Zehnder interferometers (MZI) and directional coupler (DCR) types of devices, with short active lengths are investigated.enelectro-optical modulationgallium arsenidegallium compoundsiii-v semiconductorsindium compoundslight interferometersmach-zehnder interferometersoptical directional couplersoptical switchessemiconductor quantum wellssemiconductor switches2*2 optical space switchesInGaAsP/InP mqw structures10-GHz applicationsInGaAsP-InP mqw 2*2 optical space switchesdc switching performance2*2 mach zehnder interferometersdirectional couplershort active lengths10 GHzInGaAsP-InP621conference paper
