High-quality-factor AlGaAs optical microcavities for atomic Cs and semiconductor quantum dot cavity QED experiments

摘要

High-quality-factor (Q/spl sim/10/sup 4/-10/sup 5/) AlGaAs microdisks for atomic and semiconductor quantum dot cavity QED experiments are demonstrated. Cavities embedded with InAs/InGaAs dots-in-a-well exhibit room-temperature pulsed lasing with thresholds <17uW. Continuous wave operation at room-temperature is also observed.
