Proposal for the generation of photon pairs with nonzero orbital angular momentum in a ring fiber

Quantum Physics 2023-07-19 v3 Optics

Abstract

We present a method for the generation of correlated photon pairs in desired orbital-angular-momentum states using a non-linear silica ring fiber and spontaneous parametric down-conversion. Photon-pair emission under quasi-phase-matching conditions with quantum conversion efficiency 6×1011 6\times 10^{-11} is found in a 1-m long fiber with a thermally induced χ(2)\chi^{(2)} nonlinearity in a ring-shaped core.
