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 build a numerical model of a mode-locked laser that uses a terahertz optical asymmetric demulitplexer (TOAD) as an optical modulator. The mode-locking process in the laser cavity is theoretically studied. The output pulse width and spectral characteristics under different working conditions are further shown. The laser can be used to generate high-repetition-rate pulses of different wavelength and pulse width by adjusting the offset of the SOA from the loop center in the TOAD, which provides great flexibility for the applications in optical communications and signal processing.
