    "abstract": "We present a consistent multimode theory that describes the coupling of\nsingle photons generated by collinear Type-I parametric down-conversion into\nsingle-mode optical fibers. We have calculated an analytic expression for the\nfiber diameter which maximizes the pair photon count rate. For a given focal\nlength and wavelength, a lower limit of the fiber diameter for satisfactory\ncoupling is obtained.",
