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

We report fibre-coupled CW diode pumping of 1.3 /spl mu/m GaInNAs/GaAs vertical-cavity semiconductor optical amplifiers (VCSOAs) and surface emitting lasers (VCSELs). The GaInNAs/GaAs structures are monolithic and are specifically designed for optical pumping, offering advantages in design simplification and added functionality. They allow us to demonstrate up to 1.09 dB of amplification and up to 213 /spl mu/W of 1297.2 nm laser emission. Both the 980 nm pump light and 1.3 /spl mu/m signal are coupled to/from the devices by fibers, giving promising systems-compatible demonstrators of GaInNAs-based amplifier technology.
