Abstract

Antiguided arrays have been optimized for single-spatial-mode operation to high output power. Diffraction-limited beam operation to cw power levels of 0.5 W have been reproducibly obtained. The high efficiency operation (wall plug efficiency = 20%) and demonstrated reliability make these practical devices, and useful for many applications requiring a high output power spatially coherent beam. Two-dimensional optical waveguide calculations demonstrate the mechanisms responsible for the high mode selectivity of these structures. It is also made clear why coupled-mode theory failed to predict how to obtain single-lobe phase-locked array operation, and what are the conditions to obtain stable, in-phase mode behavior.
