Abstract

A 6-element hexagonal vertical-cavity surface-emitting laser array is resonantly tuned to coherence. The far-field profile is narrowed in two-dimensions, with a Full Width at Half Maximum of 2° compared to a single-emitter with 10° FWHM. Multiple coherent outputs are possible dependent on the tuned bias condition, making this technology promising for two-dimensional mode engineering.
