Inhalt:
We measured the photoluminescence (PL) spectra of InAs/InGaAsP/InP quantum dots (QD) structures. We examined the relationship between the sample temperature and PL peak wavelength. The polarization of the excitation light was changed from the TM mode to the TE mode. We compared relations of a shift of the PL peak wavelength to the excitation light power under TM mode and TE mode excitation. We considered that the phenomenon like the band filling effect is larger for TE mode.
