WebSep 9, 2024 · This technique employs a spontaneous parametric down-conversion (SPDC) process, where one photon (pump) is split into two entangled photons (signal and idler) in a nonlinear crystal. In QIS,... Optical parametric generation (OPG) (also called "optical parametric fluorescence", or "spontaneous parametric down conversion") often precedes optical parametric amplification. In optical parametric generation, the input is one light beam of frequency ωp, and the output is two light beams of lower frequencies ωs and ωi, with the requirement ωp=ωs+ωi. These two lower-frequency beams are called the "signal" and "idler", respectively.
