Abstract

We discuss the potential of using coherently-coupled vertical cavity surface emitting laser arrays as high-intensity light sources. In particular, the design and performance of a novel two-dimensional phase-coupled grid Contact vertical cavity Surface Emitting Laser Array (C- SELA) is reported. We discuss the optical properties of the C-SELA; in addition to the usual out-of-phase array mode, we demonstrate in-phase SELA coupling. We introduce a simple physical model to describe our experimental results. Over 1.2 Watt optical power emission is obtained at room temperature from an electrically-excited 10 X 10 C-SELA. This laser array exhibited a low threshold current density of only 600 Amps/cm² and over 60% single-ended differential quantum efficiency.
