Saturable mode conversion of parametric amplification in a multimode optical fiber

The intimate interaction between phase-matched parametric amplification and strong nonlinear mode coupling in a multimode optical fiber results in a saturable mode conversion in the anti-Stokes component of the phase-matched four-wave mixing process. This novel saturable mode conversion can potentially be used in a variety of applications including the generation of exotic quantum states. (C) 2018 Author(s).
