Abstract

Recently, research to achieve narrow emission from GaN-based VCSELs has been of great interest. Sony's VCSELs with curved mirror has feature of strong lateral optical condiment, in which, causes wider emission angle. The authors obtained narrow emission angle of 3.9 degree by adopting concave mirror with large radius of curvature.
