Abstract
Diode laser sources which operate in a stable, single spatial mode to high output powers have a variety of applications including free-space communications and high-speed, high-resolution printing. These applications demand that the diode source, in addition to having a long lifetime, maintain mode stability throughout the operation of the device. Built-in positive-index-guided structures have demonstrated 0.2 W cw single spatial mode with reliable operation,1 which is limited by the width of the emitting aperture (typically 3 µm). Reliable operation at higher power levels can only be achieved by increasimitting aperture, thereby reducing the optical power density at the facet. The approach, taken here, utilizes the antiresonant reflecting optical waveguide (ARROW) structure2-4 as the built-in real-index waveguide to stabilize the lateral optical mode of the diode laser. ARROW structures, studied extensively as passive waveguides,5 are known to propagate a low loss, large spot-size optical mode. It is therefore natural to extend these concepts to stabilize the lateral mode of a diode laser.
