(2 + 1) dimensional all-optical logical gates based on soliton interaction in bulk nonlocal nonlinear media

(2 + 1) dimensional all-optical logical gates based on soliton interaction in bulk nonlocal nonlinear media

We propose the (2 + 1) dimensional all-optical logical gates based on the interaction between two components of vector solitons in nonlocal nonlinear media. The input logical states are controlled by tilting the input beams or not, and the output logical states are decided by integrated power on the...
