Ge/SiGe asymmetric Fabry-Perot quantum well electroabsorption modulators.
We demonstrate vertical-incidence electroabsorption modulators for free-space optical interconnects. The devices operate via the quantum-confined Stark effect in Ge/SiGe quantum wells grown on silicon substrates by reduced pressure chemical vapor deposition. The strong electroabsorption contrast enables use of a moderate-Q asymmetric Fabry-Perot resonant cavity, formed using a film transfer pro...
متن کاملThickness variation compensation in a Fabry–Perot modulator array using a self-tuned Fabry–Perot structure
A method is presented for compensating cavity thickness variations in conventional Fabry–Perot devices through the replacement of the input mirror with a holographic mirror, resulting in a self-tuned Fabry–Perot ~STFP! device. The technique is suitable for integrating large arrays of electro-optic Fabry–Perot modulators with silicon circuitry. Experimental results of a STFP modulator are presen...

متن کاملDesign of a new asymmetric waveguide in InP-Based multi-quantum well laser
Today, electron leakage in InP-based separate confinement laser diode has a serious effect on device performance. Control of electron leakage current is the aim of many studies in semiconductor laser industry. In this study, for the first time, a new asymmetric waveguide structure with n-interlayer for a 1.325 μm InP-based laser diode with InGaAsP multi-quantum well is proposed and theoreticall...
متن کاملBandwidth enhancement of Fabry-Perot quantum-well lasers by injection-locking
Theory and experiment for dc and small-signal electrical modulation of an injection-locked quantum-well (QW) Fabry-Perot laser are presented. Our experiment is realized by performing side-mode injection locking of a multiple-quantum-well (MQW) InGaAsP FabryPerot (FP) laser, which has the advantage of optical wavelength conversion. We first measure the dc characteristics and optical spectra of a...
