Abstract

In recent years there has been a growing interest in using standard telecommunications wavelengths for quantum communication protocols such as quantum cryptogmphy and teleportation. The low attenuation of silica fibers at these wavelengths allows for fragile photons of various sources to propagate to longer distances. A common source for many quantum communication schemes is that of entangled photons which are most easily generated by the process of spontaneous parametric downconversion. There have been many reports on how to increase the efficiency of this generation, however, there are fewer reports on how to efficiently launch these photon-pairs into single-mode fibers.
