Electro-Optical Switch Using Ge2Sb2Te5 Phase-Change Material in a Silicon MZI Structure

Abstract

We report a novel silicon MZI switch activated by the phase change of a sub-micrometer-size Ge2Sb2Te5 (GST) thin film. The phase change of GST is triggered by electrical pulses, leading to two “self-holding” switching states. Extinction ratio change of 5-dB is measured from the MZI spectrum.
