P22 – Dynamics of colliding Bragg solitons in a dual-core system with separated grating and cubic-quintic nonlinearity

We investigate the collisions of counterpropagating Bragg solitons in a dual-core optical coupler where one core has cubic-quintic nonlinearity and is coupled to another linear core equipped with a uniform Bragg grating. The outcomes of the collisions are diverse and exhibit rich dynamics.
