Patent ID: 8237152

Claim:
A white light-emitting device, comprising: a polariton light emitter disposed within an optical cavity, the optical cavity having a resonant mode corresponding to a predetermined resonant photon energy, the polariton light emitter comprising an active region forming a plurality of polaritons therein, each of the plurality of polaritons comprising an exciton coupled with a resonant photon, an energy of each of the plurality of polaritons being determined by an energy of the exciton and an energy of the resonant photon coupled therewith; and a down-converting medium disposed in close proximity to the optical cavity; wherein the polariton light emitter emits light having a wavelength corresponding to the energy of the polaritons formed in the active region, the emitted light being received by the down-converting medium; and wherein the down-converting medium converts the received light from the polariton light emitter to white light, the white light being then emitted by the down-converting medium.
