A linearly polarized coherent ultraviolet (UV) or deep UV light source is required for biochemical, medical, and other industrial applications. Current planar GaN-based UV lasers have threshold currents ∼10 kA/cm2 or higher. A polariton laser is an inversionless coherent light source operating in the strong coupling regime of light-matter interaction [1]. Exciton-polariton lasers have been realized...
When an emitter is placed in a resonant cavity, then in the strong coupling regime of light-matter interaction the degeneracy between the emitter and cavity photon is lifted, giving rise to two light-matter entangled eigenstates separated by a characteristic interaction energy (Rabi splitting) ΩVRS. These are the lower and upper exciton-polariton branches, which are the normal modes of the system...
Electrically injected polariton lasing from a GaAs-based modulation-doped microcavity diode has been demonstrated under an applied magnetic field of 7 Tesla at 30 K. Polariton lasing and condensation characteristics have been measured and analyzed.
