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 investigate optically pumped lasing of GaInNAs-based VCSELs emitting at 1.3 mum. The samples measured were full device structures including doping. Conventional p-i-n-type VCSELs showed high internal threshold excitation densities of around 10 MW/cm(2). Improvements, especially the introduction of a tunnel junction reduced the threshold to about 128 kW/cm(2) and should after further optimization enable us to realize an electrically pumped 1.3 mum VCSEL in the near future.
