What Does OPG Stand For?

OPG stands for Optical Parametric Generator

An Optical Parametric Generator (OPG) is a nonlinear optical device that converts a single input photon into a pair of entangled photons with tunable frequencies, achieved through a process called parametric down-conversion. OPGs are widely used in various applications, including quantum optics, telecommunications, and spectroscopy, due to their ability to produce coherent light sources and manipulate quantum states. Their tunability and efficiency make them essential tools in advanced research and technological development in photonics.
