Transverse Bragg Resonance Lasers: A New Approach to Mode Control in Semiconductor Lasers

John M. Choi and Amnon Yariv, California Institute of Technology

In the pursuit of a large-area, high-power diode laser that maintains efficient single-mode operation, we have proposed a device that lases in a fundamentally different manner, the transverse Bragg resonance mode. To date, our work has focused on developing an accurate model of the device, and an experimental investigation is in progress. The transverse Bragg resonance mode results from a unique approach to laser-cavity design. Rather than using lenses, mirrors or waveguides for transverse confinement, this function is provided by alternating index layers, resulting in Bragg resonant...Read full article
