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 the single-mode operation and characterization of a 1.3-m hybrid-fiber-tunable GaInNAs VCSEL. Results show that at room-temperature the device can be continuously tuned over 18.5-nm with output power up to 0.23-mW. Coupled-cavity effects were found to be a limiting factor for the tuning range. This device not only opens up potential applications in the physics of light-matter interaction, sensing and optical communications where it will, eventually, compete with InP-based VCSEL, but it is also a first step toward a tunable dilute-nitride vertical-cavity amplifier.
