Abstract

A low-finesse Fabry-Perot étalon is employed as an angularly selective filter to discriminate against the high-order spatial modes of a vertical-cavity surface-emitting laser (VCSEL) in the near field. Single-transverse-mode operation is obtained over a wide region for a 15 μm diam VCSEL.
