A miniaturized RGB-laser light engine

Abstract

ISIT developed a miniaturized RGB-laser light source based on a modular glass-silicon optics packaging platform. Although the light source is just an application example of the platform functionalities it could become an enabler for fashionable AR/MR glasses. These may find a widespread use only if consumer relevant pricing can be achieved including the light source. Increased assembly productivity for these micro opto-electrical RGB-light sources and a further reduction in their package dimensions are mandatory. We present our new approach to build miniature RGB-light sources on structured silicon wafers. The platform provides an optical bench with integrated heat spreader and emission windows enabling miniature hermetic housing for laser diodes assemblies on 8" wafers or chip level.
