Electroabsorptive/-Refractive Effects in Asymmetric Step Quantum Wells and BRAQWET Structures

Part of the ESPRIT Basic Research Series book series (ESPRIT BASIC)


The optical properties of semiconductors, for example the absorption coefficient and the refractive index, can be controlled by applying external electric fields and/or currents to the structure. This is technologically important for devices, such as electrically controlled intensity and phase modulators, directional couplers and devices for wavelength multiplexed systems.
