Analysis of photoluminescent properties of InAs/InGaAsP/InP quantum dots structure

We measured photoluminescence (PL) spectra of InAs/InGaAsP/InP quantum dots structures. We examined the PL peak shift changing the polarization of excitation light from p-polarization to s-polarization and the excitation light power. From the results, we estimated that the phonon emission according to the increase in TM component of the p-polarization.
