Abstract :
A normally-off asymmetry Fabry-Perot reflection modulator using a lifted-off GaAs/AlGaAs multiple-quantum well-structure is reported. The 2 mu m thick epitaxial layer was bonded to a silicon wafer coated with gold, which served as the rear mirror and as an electrical contact. Modulation ratios of 3.4:1 with 5 V bias and 4.3:1 with 12 V bias were obtained with an insertion loss of 4.3 dB at 12 V.
