Abstract
We have investigated polarization-dependent photoluminescence in InP/InAs/I nP quantum wires directly formed on the top of InP substrates. With excitat ion laser intensity we have observed an anomalously large blueshift of the photoluminescence peak using a cw laser with extremely low intensities. We have also observed evidence of band-gap renormalization. In addition, we ha ve measured two-photon luminescence spectra and confirmed their dependence on photoluminescence polarization.
