Abstract
We report results of measurements of optically modulated optical transmittance of GaAs doping superlattices. The data extend over a spectral region of 1.39–1.58 eV. We find that the peak transmission modulation reaches 21% for a 2.6‐μm‐thick sample and an optical pump power density of 2 at room temperature. We interpret our data in the framework of a simple semiclassical model that includes the Franz–Keldysh effect both below and above the bulk GaAs band gap, as well as band filling and band shrinkage effects.This publication has 10 references indexed in Scilit:
