Abstract
A light-emitting device includes a semiconductor substrate, a surface-emitting semiconductor light source on the semiconductor substrate, a monolithic first dielectric, and a second dielectric. The monolithic first dielectric is transparent to light emitted by the light source and includes first and second micro-lenses adjacent an aperture of the light source and having axes parallel to and offset from an axis of a beam of light emitted by the light source, and a saddle-shaped lens over the aperture of the light source. The saddle-shaped lens connects the first and second micro-lenses and reshapes the beam of light emitted by the light source to have a high aspect ratio. The second dielectric is transparent to light emitted by the light source and encapsulates a light emission surface of the saddle-shaped lens. The second dielectric has a higher refractive index than the monolithic first dielectric.
