Two-Photon Polarization Interference for Pulsed SPDC in a PPKTP Waveguide
arXiv:0810.0998 · doi:10.1103/PhysRevA.79.043836
Abstract
We study the spectral properties of Spontaneous Parametric Down Conversion in a periodically poled waveguided structure of KTP crystal pumped by ultra-short pulses. Our theoretical analysis reveals a strongly multimode and asymmetric structure of the two-photon spectral amplitude for type-II SPDC. Experimental evidence, based on Hong-Ou-Mandel polarization interference with narrowband filtering, confirms this result.
