Ge and GeSi electroabsorption modulator arrays via strain and composition engineering
… for telecommunications and sensing applications. Electroabsorption modulators allow fast modulation, small device footprint, and low power consumption. Epitaxially grown GeSi films on SOI substrates are a suitable materials platform for integrated modulator applications. A modulator's operation …

High-Speed Modulation of Semiconductor Lasers and Modulators
… laser system. Second, we investigate integrated electroabsorption modulator-lasers. They are more compact and have very good high-speed performance. We study injection locking using these integrated devices, presenting a novel data acquisition method by directly measuring the modulator section …
