Determination of operating parameters for a GaAs-based polariton laser
MetadataShow full item record
We report on a systematic study of the phase transitions to polariton condensation (PC) and further to cavity lasing in a GaAs-based microcavity with respect to exciton-cavity detuning and lattice temperature. Using far field and time-resolved spectroscopy, we determined the parameter space in which PC can be achieved and the corresponding variation of PC threshold power. We found a lower bound of -12 meV for the exciton-cavity detuning and an upper bound of 90 K for the lattice temperature.
