F. Kh. Abdullaev, B. A. Umarov, Exact solitonic solutions for optical media with χ(2) nonlinearity and PT-symmetric potentials, Journal of Physics: Conference Series 553 (2014)

We study the χ(2) system of equations with the PT-symmetric potentials. We obtain exact solitary wave solutions for this system for some forms of the PT-symmetric potentials
