Optical interference effect of a thick absorbing LT-GaAs layer on a Bragg reflector
Optical interference effect of a thick absorbing LT-GaAs layer on a Bragg reflector Near-infrared reflectance spectra of 5 μm thick low-temperature (LT) GaAs films on GaAs/AlAs Bragg reflectors (BRs) have been studied by model calculations as a function of the linear absorption coefficient of the films αf. With increasing αf, the reflectance of the...
