METHOD OF MANUFACTURING OPTIMIZED LIGHT DEVICES USING ARTIFICIAL MATERIALS

摘要

The present invention relates to a method of manufacturing light devices. More particularly, it is aimed at allowing the manufacture of light emitters with improved efficiency by using artificial materials making it possible to effect anti-reflection or high-reflectivity treatments. To this end, sub-wavelength structures are etched on one of the ends of an emissive cavity, making it possible to control the external face. The invention applies to any light emitter and hence in particular to lasers, and more particularly still to quantum cascade lasers (or QCLs). Moreover, the method of manufacture according to the invention is preferably collective.
