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.

We demonstrate a novel integrated optical delay line approach based on silicon subwavelength gratings (SWGs). By 30% change in duty-cycle of SWG waveguides with a same length of 8mm to control their group index, up to ~30ps time-delay was achieved.
