Near-zero anomalous dispersion Ge11.5As24Se64.5 glass nanowires for correlated photon pair generation: design and analysis

Gai, X; Wang, R. P.; Xiong, C; Steel, M. J.; Eggleton, B. J.; Luther-Davies, B


We show that highly nonlinear chalcogenide glass nanowire waveguides with near-zero anomalous dispersion should be capable of generating correlated photon-pairs by spontaneous four-wave mixing at frequencies detuned by over 17 THz from the pump where Raman noise is absent. In this region we predict a photon pair correlation of >100, a figure of merit >10 and brightness of ~8×108 pairs/s over a bandwidth of >15 THz in nanowires with group velocity dispersion of <5 ps∙km−1nm−1. We present designs...[Show more]
