Room temperature circularly polarized electroluminescence is observed from bulk GaN-based double-heterostructure edge-emitting light emitting diodes operated with continuous-wave spin-polarized electrical injection. The measured in-plane magnetizing field-dependent output circular polarization in the quasi-Voigt geometry is coincident with the hysteresis characteristics of the spin-injector confirming...
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...
