SEMICONDUCTOR OPTICAL MODULATOR

Abstract: a semiconductor optical modulator is formed by stacking a plurality of semiconductor layers including an optical modulation layer on a semiconductor substrate and emits light by modulating an intensity or a phase of light incident on the optical modulation layer. the optical modulation layer is formed using a digital alloy in which the semiconductor layers having a layer thickness of two or more atomic layers and having different constituent elements or composition ratios are alternately and repeatedly stacked.
