US 2025/0160090 A1 · OPTICAL DEVICES COMPRISING NANOROD LIGHT EMITTERS ON A SUBSTRATE

Abstract

There is provided a light source to emit an output light along an output path. The light source includes a substrate, and a plurality of light emitters disposed on the substrate in the output path. The light emitters each have a footprint on the substrate and extend away from the substrate laterally to the output path. The light emitters each include a quantum well to emit the output light when the light emitter is electrically biased. Moreover, the light emitters each have a refractive index higher than a corresponding refractive index of an environment outside of and abutting the light emitters. The light emitters may each include a nanorod, and each pair of neighboring nanorods may be spaced from one another along the output path by a distance being about λn/2, where λ is a wavelength of the output light and n is a natural number.
