901 nm Lithographic vertical‐cavity surface‐emitting laser with stable single‐lobed beam pattern
Electronics Letters2015Vol. 51(21), pp. 1683–1684
Abstract
Data are presented on 901 nm lithographic vertical‐cavity surface‐emitting lasers (VCSELs) demonstrating high efficiency for small VCSEL sizes, and stable beam patterns. Power conversion efficiency >40% is obtained for VCSELs ranging in size from 6 to 2 µm diameter. The 2 µm diameter VCSELs produce output powers in excess of 6.5 mW, and produce single‐lobed far‐field radiation patterns over the full range of operation.
