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 miniature variable optical attenuator employing a ferrofluid actuator/shutter combination located between lensed optical fibers. The VOA consists of an opaque, undiluted ferrofluid plug actuator inside a microfluidic channel. The ferrofluid plug position is translated by a variable magnetic field generated from a miniature electromagnet. The ferrofluid plug actuator in turn displaces a second oil-diluted ferrofluid plug acting as an optical shutter. The position of the shutter controls the optical power coupled between the input and output fibers.
