    "abstract": "A new method for generating entangled photons with controllable frequency\ncorrelation via spontaneous parametric down-conversion (SPDC) is presented. The\nmethod entails initiating counter-propagating SPDC in a single-mode nonlinear\nwaveguide by pumping with a pulsed beam perpendicular to the waveguide. The\nmethod offers several advantages over other schemes, including the ability to\ngenerate frequency-correlated photon pairs regardless of the dispersion\ncharacteristics of the system. Numerical evidence demonstrates the improvement\nprovided by this source in the special case of frequency-correlated two-photon\nstates.",
