Polarization-Sensitive Electroabsorption in GaAs/AlGaAs Quantum Well Waveguides,"
Appl. Phys. Lett. 47, 1148-1150 (1985).
We report the first measurements
of perpendicular field electroabsorption (quantum confined Stark effect) in GaAs/AlGaAs
quantum wells for light propagating parallel to the plane of the layers. This geometry is
well suited for integrated optics. The absorption edge shifts to longer wavelengths with
increasing field by as much as 40 meV, giving a modulation depth > 10 dB. The strong
dichroism present in this geometry is retained even at high fields, making
polarization-sensitive electro-optical devices possible. we also demonstrate in the
waveguide geometry optical bistability due to the self-electro-optic effect with 20:1
