High quantum efficiency photodetectors for quantum instruments
Deborah J. Jackson, G. Hockney, Jonathan P. Dowling · Frontiers in Optics · 2003
Achieving detector quantum efficiencies of 90% or greater is enabling for many experiments involving squeezed and entangled light. This paper discusses why poor quantum efficiency reduces one’s ability to exploit squeezed light and describes a light trap approach to improving the detection quantum efficiency.
