Low-Threshold and Narrow Linewidth Two-Electrode MQW Laterally Coupled Distributed Feedback Lasers at 1550 nm

Not Accessible

Your library or personal account may give you access

Abstract

We demonstrate for the first time a low-threshold and narrow-linewidth multi-electrode distributed feedback laser with third-order surface gratings operating at 1550 nm. Stable single-mode operation is obtained with SMSR of over 50 dB.
