Open Access research that is better understanding human-computer interaction...

Strathprints makes available scholarly Open Access content by researchers in the Department of Computer & Information Sciences, including those researching information retrieval, information behaviour, user behaviour and ubiquitous computing.

The Department of Computer & Information Sciences hosts The Mobiquitous Lab, which investigates user behaviour on mobile devices and emerging ubiquitous computing paradigms. The Strathclyde iSchool Research Group specialises in understanding how people search for information and explores interactive search tools that support their information seeking and retrieval tasks, this also includes research into information behaviour and engagement.

Abstract

We demonstrate a high output power passively mode-locked distributed Bragg reflector laser with integrated tapered semiconductor optical amplifier, operating at 1.5 μm. These devices are based on an optimized low-optical-confinement AlGaInAs/InP epitaxial material with a three quantum wells active region and a passive far-field reduction layer. The device generates nearly transform-limited pulses with minimum pulse duration of 4.3 ps at 40-GHz repetition rate. An average output power of 200 mW with a corresponding output peak power of >;1.2 W is achieved.
