Polarization Effects of Ecitation Light Source on Photoluminescence Spectra of INGAASP/INP Quantum Well Structures

We have observed the photoluminescence (PL) spectra of InGaAsP/InP quantum well structures. PL spectra peak movements for TE or TM mode excitation are observed by changing the incident angle of the excitation light. The PL spectra peak for TM mode excitation moves toward the longer wavelength as compared with that estimated by the heat dissipation.
