We study the existence of soliton pairs in nonlocal nonlinear coupler and the effects of nonlocal nonlinearity on the stability and types of soliton pairs. Bright soliton, dipole soliton, periodic soliton, double soliton and dark soliton are found, and many kinds of antisymmetric, symmetric and asymmetric solitons can be obtained by adjusting the nonlinear parameters or coupling coefficients. In addition, the stability of the exact bright solitary wave solutions and dipole-mode solitary wave solutions with the white noise perturbation are also investigated numerically. It is investigated that the energy flow and the Hamiltonian, and the energy flow are related to the nonlocal parameter. Moreover, We also obtain some Airy-like solitons by numerical method.
