What Does 4WM Stand For?

4WM stands for Four Wave Mixing

4WM, or Four Wave Mixing, is a nonlinear optical process in which two or more wavelengths of light interact within a medium to produce new wavelengths. This phenomenon is utilized in various applications, including telecommunications and spectroscopy, to enhance signal processing and enable frequency generation. By efficiently converting and mixing light waves, 4WM plays a crucial role in advancing optical technologies and improving communication systems.
