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

The performance of a ring-resonator based passive wavelength router, suitable for optical networking at chip level, is evaluated through bit error rate measurements in single channel 10 Gb/s and 3-channel 10 Gb/s WDM configurations. As the routing path involves a different number of routing elements, depending on the wavelength used for the propagating signal, the performance of three output ports with respect to a specified input one are experimentally evaluated and discussed. Measurements show that low rejection on the filter elements due to fabrication issues mostly affect the channel on the through path with respect to the dropped ones.
