Distinct Types of Coupled Propagation of Beams in Kerr Type Nonlinear Media
Ram Krishna Sarkar and Surya Mallick

The paper investigates coupled propagation of two co-propagating incoherent beams in Kerr type nonlinear media, for different values of radial inhomogeneity. In this paper, we have proposed existence lines for distinct types of coupled propagation, including formation of rhythmic and nonrhythmic breather pairs. Furthermore, a detailed explanation on coupled propagation has been provided and influence of initial curvatures on the coupled propagation has also been discussed.

Keywords: radial inhomogeneity, breather pair, Kerr type nonlinear media, coupled propagation, existence line
