Measurement of electro-refraction in GaAs/AlGaAs multiple quantum well waveguide structures

Measurement of electro-refraction in GaAs/AlGaAs multiple quantum well waveguide structures

Presents a direct approach to precisely measure changes in refractive index (/spl Delta/n) of GaAs/AlGaAs Multiple Quantum Well (MQW) wave guide structures as a function of applied electric field across the MQW layers. The results of /spl Delta/n(E) are useful for developing electro-optic quantum we...

Zusammenfassung:Presents a direct approach to precisely measure changes in refractive index (/spl Delta/n) of GaAs/AlGaAs Multiple Quantum Well (MQW) wave guide structures as a function of applied electric field across the MQW layers. The results of /spl Delta/n(E) are useful for developing electro-optic quantum well devices.
