Abstract
Miniaturized RGB-laser light sources could become an enabler for fashionable augmented and mixed reality glasses. 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. These are part of our optical packaging platform that enables efficient assemblies with controlled working environments for long term performance of semiconductor laser sources. 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.
