Low Loss InGaAs/Inp Multiple Quantum Well Optical Electroabsorption Waveguide Modulator.
01 January 1987
An optical electroabsorption waveguide modulator is described based on the quantum confined Stark effect in an InGaAs/InP multiple quantum well (MQW) waveguide. The optical modulator has a high on/off ratio (47:1) with very low insertion loss (2.9 dB) and a 3-dB modulation bandwidth of 3.0 GHz at 0.1 mW optical input power.
