The IEEE Photonics Journal has chosen the paper "60% Efficient Monolithically Wavelength-Stabilized 970-nm DBR Broad-Area Lasers" as 2022 Editor's Choice. The open-access publication by Paul Crump, M. J. Miah, Martin Wilkens, Jörg Fricke, Hans Wenzel and Andrea Knigge describes the progress made at Ferdinand-Braun-Institute in high-power diode lasers.
Here's how Editor in Chief Gabriella Cincotti explained her choice: "This paper represents several key points critical to PJ. Rapid publication and open access via PJ is well justified, as it represents significant progress in the high-power diode laser field, exploiting progress in device understanding and epitaxial semiconductor growth and device technology to enable step-improved performance, reporting the first devices to deliver more than 20 W optical output in a narrow spectral line, while maintaining more than 60% power conversion efficiency.”
The paper is an expanded version of a selected post-deadline paper from the closing presentation at the 2021 International Semiconductor Laser Conference and also the opening paper of the recently published special issue of the IEEE Photonics Journal.
