Fiber-Based Multichannel Correlated Photon-Pair Source with High Efficiency and Low Crosstalk
Yuzhu Sun, Yu‐Ping Huang, Neal N. Oza, Prem Kumar · 2013
We present a fiber-based multichannel source of correlated photon pairs in the telecommunication O-band. Coincidence-to-accidental ratios >100 (≃1) are measured between the paired (unpaired) signal-idler channels.
