Lasing threshold doubling at the crossover from strong to weak coupling regime in GaAs microcavity

Tsotsis, P; Eldridge, PS; Gao, Tingge; Tsintzos, S.I; Hatzopoulos, Z; Savvidis, P.G

Description

In a polariton, laser coherent monochromatic light is produced by a low-energy state of the system at the bottom of a polariton ‘trap’, where a condensate of polaritons is formed, requiring no conventional population inversion. Following the recent realization of polariton light-emitting diodes (LEDs) based on GaAs microcavities (MCs) operating up to room temperature, efforts have been directed towards the demonstration of an electrically injected polariton laser. However, until now,...[Show more]
