Abstract:
A light emitting device includes a substrate, a buffer layer, a first active layer, and a plurality of mesa regions. A portion of the first active layer includes a first electrical polarity. The plurality of mesa regions includes at least a portion of the first active layer, a light emitting region on the portion of the first active layer, and a second active layer on the light emitting region. A portion of the second active layer includes a second electrical polarity. The light emitting region is configured to emit light which has a target wavelength between 200 nm to 300 nm. A thickness of the light emitting region is a multiple of the target wavelength, and a dimension of the light emitting region parallel to the thickness is smaller than 10 times the target wavelength, such that the emitted light is confined to fewer than 10 transverse modes.

Claim (Index 11):
A method for manufacturing a light emitting device comprising:\n providing a substrate, the substrate having a substrate area comprising a substrate length and a substrate width; forming a buffer layer on the substrate; forming a first active layer on the buffer layer, at least a first portion of the first active layer comprising a first electrical polarity; forming a light emitting region on the first active layer, the light emitting region being configured to emit light, the emitted light having a target wavelength, and the target wavelength being between 200 nm and 300 nm; forming a second active layer on the light emitting region, at least a first portion of the second active layer comprising a second electrical polarity; forming a first electrical contact layer on the second active layer; removing a portion of the first electrical contact layer, a third portion of the second active layer, a portion of the light emitting region and a third portion of the first active layer in an area that is outside of a plurality of mesa areas and that surrounds the plurality of mesa areas to form a plurality of mesas, wherein each of the plurality of mesas comprises:\n a second portion of the first active layer, a second portion of the light emitting region, a second portion of the second active layer and a second portion of the first electrical contact, the respective portions each having an area that is equal to the mesa area, the mesa having a mesa top surface and mesa sidewall surfaces, the mesa area comprising a mesa length and a mesa width, the mesa area being smaller than the substrate area, the mesa width being a multiple of the target wavelength, and the mesa width confining the emitted light from the light emitting region to fewer than 10 transverse modes; \n forming a second electrical contact layer on an exposed portion of the first active layer; forming a passivation layer that is: (i) on the first electrical contact layer, (ii) on the second electrical contact layer, (iii) on a remaining exposed portion of the first active layer, and (iv) on the mesa sidewall surfaces; exposing the first electrical contact layer; exposing the second electrical contact layer; forming a first terminal contact layer on the first electrical contact layer; and forming a second terminal contact layer on the second electrical contact layer.
