Multiphase patterns in a degenerate nonlinear oscillator

Abstract

Degenerate four-wave mixing (DFWM) oscillators are phase-bistable devices. In such systems, two equivalent states, of equal intensities but opposite phases can be generated. When the cavity Fresnel number is large, different regions of the beam transverse section can have different phases, leading to phase patterns like phase fronts (or domain walls), i.e. 1D structures separating regions with opposite phase that manifest as dark lines (as the phase jumps by π across the wall), phase domains, and phase solitons, among others.
