Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

A simple way to improve the output power of singlemode tunable VCSELs is demonstrated. It is based on a master oscillator power amplifier (MOPA)-like embodiment of a fibre-VCSEL. The reported device, operating at 1.55 mu m, uses a single pump source to photo-excite both a semiconductor structure and a doped fibre without compromise in compactness. Initial results show continuous tunability over 11 nm and. bre-coupled output power of 3.1 mW. It is noted that this approach can be extended to any part of the spectrum for which rare-earth doped optical fibres are available.
