Source: ResearchGate Understanding Parametric Fluorescence in Optical Parametric Amplifiers An optical parametric amplifier can exhibit parametric fluorescence, which is the emission of light even in the absence of a signal and idler input. This phenomenon, rooted in quantum mechanics, is caused by vacuum fluctuations of the optical field entering the device’s open input ports. In […]
