Transverse Effects under Four-Wave Coupling in the Nonlinear Fabry–Perot Interferometer

Specific features of the light-beam transverse structure transformation in the process of four-wave coupling in the Fabry–Perot interferometer with a resonant nonlinearity under conditions of bifurcation of the symmetry breaking and optical bistability are analyzed. The asymmetric regimes of the interaction, characterized by a difference both in the integrated transmission functions of the nonlinear interferometer for two light beams with equal intensities and in the spatial intensity distribution at the exit of the interferometer, are considered
