Electrorefraction In Semiconductor Quantum Wells

We have measured electric-field-induced changes in refractive index in GaAs- and InP-based quantum well heterostructures. Excitonic effects provide index changes one to two orders of magnitude larger than in corresponding bulk semiconductors. This enhancement can be applied to low-voltage, compact devices for electro-optic phase modulation.
