Characterizing Nonlocal Dispersion Compensation In Deployed Telecommunications Fiber
APPLIED PHYSICS LETTERS(2019)
Abstract
Propagation of broadband photon pairs over deployed telecommunication fibers is used to achieve nonlocal dispersion compensation without the deliberate introduction of negative dispersion. This is made possible by exploiting time-energy entanglement and the positive and negative dispersive properties of the fiber. We demonstrate the preservation of photon timing correlations after transmission over two multi-segment 10 km spans of deployed fiber and up to 80 km of laboratory-based fiber. (C) 2019 Author(s).
