Abstract

A high contrast, low power optical reflection modulator with an InGaAs/GaAs strained-layer multiple quantum well (MQW) nonlinear spacer is demonstrated. Taking advantage of large absorptive and dispersive nonlinearities near the exciton peak, on/off contrast ratios exceeding 29 dB are achieved with submilliwatt pump powers at room temperature.
