Abstract
The present invention claims a unique way to pattern an optical microstructure immediately on top of a mass produced light-emitting device, such as a light emitting diode (LED), a vertical cavity surface emitting laser (VCSEL) or a photo detector, for the purpose of efficient coupling of light to or from the active region of the light-emitting device. The invention addresses the need to effectively and efficiently extract light from the light-emitting optoelectronic device. Finally, the invention allows for the optical microstructure to be deposited and patterned directly over the light-emitting device contained on a suitable substrate, such as a wafer.
