781 Mbit/s photon-counting optical communications using a superconducting nanowire detector.

چکیده
We demonstrate 1550 nm photon-counting optical communications with a NbN-nanowire superconducting single-photon detector. Source data are encoded with a rate-1/2 forward-error correcting code and transmitted by use of 32-ary pulse-position modulation at 5 and 10 GHz slot rates. Error-free performance is obtained with -0.5 detected photon per source bit at a source data rate of 781 Mbits/s. To the best of our knowledge, this is the highest reported data rate for a photon-counting receiver.

1.25-Gbit/s photon-counting optical communications using a two- element superconducting nanowire single photon detector
The sensitivity of a high-rate photon-counting optical communications link depends on the performance of the photon counter used to detect the optical signal. In this paper, we focus on ways to reduce the effect of blocking, which is loss due to time periods in which the photon counter is inactive following a preceding detection event. This blocking loss can be reduced by using an array of phot...
متن کاملSuperconducting Nanowire Photon-Counting Detectors for Optical Communications
Photon-counting detectors can be used in optical communications links to provide a large enhancement in receiver sensitivity over conventional photodetectors at near-infrared wavelengths (1.3–1.55 microns) [1]. However, the highest data rate that has been demonstrated to date using these techniques is about 100 kbits/sec for a receiver consisting of a single InGaAs avalanche photodiode (APD), w...

متن کاملEnhancing Detection Efficiency by Applying an Optical Cavity Structure in a Superconducting Nanowire Single-Photon Detector
We report on the enhancement of system detection efficiency in a superconducting nanowire single-photon detector (SNSPD) by applying the optical cavity structure. The nanowire was made using 4nm-thick NbN thin films and covered with an SiO cavity and Au mirror designed for 1300–1600 nm wavelengths. The device is mounted into fibercoupled packages, and installed in a practical multichannel syste...
