Abstract

GaInP microdisks contained InP/GaInP quantum dots having lateral size ∼150?nm and 1-5 μm-2 were investigated with help of microphotoluminescence technique. Experiments carried out in confocal, time-resolved and lowerature modes. Comparison of results allowed to conclude that overlap of quantum dot emission area with whispering gallery mode antinode results in faster luminescence lifetime (Purcell effect). Whispering gallery mode lasing was detected. Obtained threshold power values were following 6μW (Q=4500, T=8.5K) and 0.4μW (Q=7400, T=80K).
