Strathclyde Open Access research that creates ripples...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of research papers by University of Strathclyde researchers, including by Strathclyde physicists involved in observing gravitational waves and black hole mergers as part of the Laser Interferometer Gravitational-Wave Observatory (LIGO) - but also other internationally significant research from the Department of Physics. Discover why Strathclyde's physics research is making ripples...

Strathprints also exposes world leading research from the Faculties of Science, Engineering, Humanities & Social Sciences, and from the Strathclyde Business School.

Tunable, narrow-band light source in the 1.25 mu m region based on broad-area quantum dot lasers with feedback

Abstract

The coherence of broad-area laser diodes with quantum dot gain medium is improved by frequency-selective feedback. A linewidth of 5-10 GHz at power levels of 10-140 mW is achieved in the wavelength region around 1240 nm, where no other good semiconductor lasers are available. The tuning range is at least 20 nm.
