Title

Focusing Effect in Multimode Vertical Cavity Surface Emitting Lasers by Parallel Trenches Surface Profiling

Publication Type

Conference Proceeding Article

Publication Date

7-2005

Abstract

Surface profiling of parallel trenches is shown to be capable of introducing a transverse waveguiding effect to the optical modes of a gain-guided VCSEL, resulting in a dramatic reduction of emission spot-size and spatial filamentation.
