Coherent Light Emission

Caption

Coherent light emission of one-dimensional polaritons in the quantum well nanocavity. Above the lasing threshold, the interference pattern, which is associated with Fabry-Pérot cavity modes along the long axis of the nanorod (left inset), is observed. The radial quantum wells integrated on the sidewall of the nanorod (right inset) provide the enhanced thermal stability and oscillator strength of excitons to achieve the room-temperature polariton lasing.
