What Does PFWM Stand For?

PFWM stands for Parametric Four Wave Mixing

PFWM, or Parametric Four Wave Mixing, is a nonlinear optical process in which two strong pump waves interact with a medium to generate two new signal waves at different frequencies. This technique is widely used in telecommunications and photonics for applications such as signal amplification, wavelength conversion, and the generation of entangled photons, enabling advancements in optical communication systems and quantum information technologies.
