Two-Crystal Configuration for Frequency-Converted Spontaneous Parametric Down Conversion
Abstract
Frequency-converted spontaneous parametric down conversion (SPDC) produces polarization entangled photons with high purity, visibility, and heralding efficiency over many wavelengths. Our two-crystal setup simplifies focusing optimization allowing maximum brightness while achieving 99% purity and visibility.
