Abstract :
Reports the realisation of a 2×2 switch using a Mach-Zehnder interferometer with tunable coupler sections. The structure is based on a GaAs-AlGaAs double hetero-structure with SnO2-doped In2O3 electrodes. At a wave-length of 1.15 μm, this device is characterised by a low switching voltage of 7.5 V and a low loss of 4 dB/cm. A high extinction ratio of 20 dB can be achieved
