Abstract

A device emits radiation at a predetermined wavelength. The device includes a light-emitting structure which generates the radiation. The device further includes at least one reflective edge in radiative communication with the light-emitting structure, the reflective edge having a dielectric portion. The device further includes at least one electrical contact extending through the dielectric portion of the reflective edge, the contact in electrical communication with the light-emitting structure.
