Solitons in a PT-symmetric χ(2) coupler.


We consider the existence and stability of solitons in a χ(2) coupler. Both the fundamental and second harmonics (SHs) undergo gain in one of the coupler cores and are absorbed in the other one. The gain and loss are balanced, creating a parity-time (PT) symmetric configuration. We present two types of families of PT-symmetric solitons having equal and… (More)
