In this paper we focus on the development of such devices for optical time-division multiplexing (OTDM) systems. Interferometer arrangements consisting of one or two SLAs are very attractive for this purpose. Here the cross-phase modulation due to the gain-saturation nonlinearity of SLAs provides the differential phase shift required for interferometric switching.enelectro-optical modulationelectro-optical switchesintegrated optoelectronicslight interferometersoptical communication equipmentoptical information processingoptical saturationphase modulationsemiconductor laserstime division multiplexingmonolithically integrated semiconductor laser amplifier structuresoptical signal processingoptical networksoptical time-division multiplexingtdminterferometer arrangementscross-phase modulationgain-saturation nonlinearityphase shiftinterferometric switching621conference paper
