Quantum Well Optical Modulators and Seed All-Optical Switches
When thin (e.g., 100 Å ) layers of the semiconductors GaAs and GaA1As are grown alternately one on top of the other, many interesting physical effects result. One is a new electro-absorption mechanism which can be used for high-speed optical modulators or low-energy all-optical switches compatible with laser diodes.
