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

The gain and dynamic behaviour of InGaAsN quantum well (QW) lasers is investigated. A comparison of simulated material gain of 1300 nm InGaAsN, AlGaInAs and InGaAsP quantum wells is made to gauge its gain performance. The small-signal modulation characteristics of a 250 µm MQW ridge waveguide (RWG) InGaAsN laser are presented and high-temperature characteristics are shown.
