Scientists studied how different types of light interact in an optical fiber. They found that certain types of light, like coherent anti-Stokes Raman scattering, are affected by the presence of other types of light, like inverse Raman absorption. They also observed new types of light emissions, such as second order coherent Stokes Raman scattering. These findings help us understand how light behaves in optical fibers and can be useful for improving technologies like fiber optic communication.
