Abstract
In this paper, vector dark solitons with two colors are demonstrated in nonlocal nonlinear Kerr medium. Using Lagrangian method and rectangular profile of nonlocal response of the media, solutions of the solitons are obtained analytically. The stability of the solitons is also studied numerically, which confirms the analytical results. Nonlocality can suppress instability induced by the difference of diffraction coefficients, leading to formation of stationary two-color vector dark solitons which are always unstable in local nonlinear media.
