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 x 10(-11) is found in a 1-m long fiber with a thermally induced chi((2)) nonlinearity in a ring-shaped core.
