Abstract
We optimise the packaging of Watt-power tapered amplifiers in order to offer high coupling efficiency into single mode fibre. The conclusions of a lab study were used to inform the build and manufacturing procedure for integration inside a 14-pin butterfly module, seeded with an input fibre. Careful thermal management and robust alignment is critical for reliable operation. We demonstrate devices with the output externally coupled into PM fibre with efficiencies exceeding 60% and powers above 1 W at 780 nm. The devices are currently being used to drive a rubidium magneto-optic trap.

Peter J. Schlosser is currently a Senior Researcher at the Fraunhofer Centre for Applied Photonics, a department of Fraunhofer Uk Research Ltd, based in Glasgow, UK. He graduated with the Ph.D. degree in Physics at the University of Strathclyde, Institute of Photonics in 2011. He joined Fraunhofer Uk Research Ltd in 2014 at the Centre for Applied Photonics (CAP) in Glasgow, where his work is focussed on research and development of laser-based systems, spanning from the deep UV to the long wave mid-IR spectral range and operating in the cw or pulsed regimes. Target applications address requirements in sectors such as Quantum Technologies, Communications, Space, Medical, Defence and more. He has an established track record that includes collaborative research, funded by direct industrial contracting, government innovation funds (UK, EU), and ESA projects.
