Abstract

The process of propagation and formation of pulse pairs in a quadratically nonlinear crystal with two waveguides is investigated when parameters related to the position of the waveguides relative to each other, delay and phase ratio between pulses change. A change in the pulse propagation mode during the approach of waveguides and the dependence of the nature of the interaction between the pulses on the initial phase ratio were found.
