Abstract
Microcavity comprising two reflectors, at least one semiconductor layer separating said reflectors and a semiconductor quantum well wherein at least one of said reflectors and of said at least one semiconductor layer comprises a structure which is adjusted to localize a polariton in said microcavity.
Claims6
A photon emitting device, comprising:
- a microcavity, wherein the microcavity comprises:
- two reflectors;
- at least one semiconductor layer separating the two reflectors;
- and
- a semiconductor quantum well,
- wherein at least one of the two reflectors and of the at least one semiconductor layer comprises a structure that is adjusted to localize a polariton in the microcavity;
- and
- a light source, wherein the light source is adjusted to emit radiation onto the microcavity at a wavelength that is resonant or slightly red shifted with respect the fundamental resonance of a polariton in the microcavity.
