LOW DIVERGENCE VERTICAL CAVITY SURFACE EMITTING LASERS, AND MODULES AND HOST DEVICES INCORPORATING THE SAME

The disclosure describes VCSELs operable to produce very narrow divergent light beams. The narrow divergent beam can be obtained, in part, by incorporating an additional epitaxial layer so as to increase the cavity length of the VCSEL. The increased cavity length can result in higher power in fewer...
