  • Abstract
    A new type of two-dimensional distributed Bragg reflector laser (2D-DBR) has been proposed and demonstrated based on analysis of earlier lasers. Threshold currents are 1/9th of earlier values and differential quantum efficiency is up by 2.5 times, while keeping the highly collimated output beam characteristics (0.9° × 3.2°).
