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

A compact silicon photonics multi-wavelength filter is demonstrated using superimposed sidewall Bragg gratings. We show arbitrary wavelength spacing with 8 superimposed gratings on a total footprint that is equivalent to a single Bragg grating device.
