Not Accessible

Your library or personal account may give you access

Abstract

We demonstrate single-mode laterally coupled distributed-feedback diode lasers at 2.05 µm employing low-loss etched gratings. Single-facet CW output exceeds 50 mW near room temperature with linewidth below 1 MHz over 10-ms observation times.
