Samenvatting
Nanowire superconducting single photon detectors (SSPDs) are unique detectors for
many applications in quantum information and communications technology, owing to
their ultrafast photoresponse, low dark count rate and low timing jitter. However, they
have limited detection efficiency due to small optical absorption in ultrathin wires. A
promising approach to increase the photon absorption in SSPDs, is integrating them
with advanced optical structures. We demonstrate the successful integration of SSPDs
with optical microcavities based on GaAs/AlAs Bragg mirrors. Characterization of
these devices reveals clear cavity enhancement of the detection efficiency, resulting in a
peak value of18% at 2=l300nm and T=4.2K
