摘要: Dispersions of field-induced variations in refractive index and absorption coefficient a GaAs/AlGaAs quantum well structure are obtained with electroreflectance transmission measurements at room temperature. The result indicates possibility an electroabsorption modulator without frequency chirping, operating particular wavelength near excitonic gap.
