From: Distribution of entangled photon pairs over few-mode fibers
Measured single channel count rates and coincidence count rates of polarization entangled photon pairs. The data are plotted as functions of the relative angle of the polarization entanglement analyzers, and the dashed lines are the best fit of the coincidence rates. (a) Is the results for photon pairs directly output from the source, (b) and (c) are the results when the signal photons are distributed over the FMF in LP 01 mode and LP 11a mode, respectively.
