Open Access research with a European policy impact...

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 European Policies Research Centre (EPRC).

EPRC is a leading institute in Europe for comparative research on public policy, with a particular focus on regional development policies. Spanning 30 European countries, EPRC research programmes have a strong emphasis on applied research and knowledge exchange, including the provision of policy advice to EU institutions and national and sub-national government authorities throughout Europe.

Abstract

We report a multi-wavelength passive filter working in the 1.3 μm range, fabricated by a post-growth technique based on the combined lateral-vertical steam oxidation of AlGaAs layers within a microcavity. Wafers are photolithographically patterned and etched through the top to create mesa structures which are oxidized from both edges, and control of resonant wavelength is achieved through mesa width, thickness and compositional control of intracavity layers to be oxidized, and oxidation conditions. Microreflectivity measurements of the processed devices show that in this wavelength range it is possible using this approach to control the resonant wavelength over a range of about 52 nm.
