We present a generalized Snell's law that governs grey soliton refraction at the interface separating two defocusing Kerr media. The analysis, based on the Helmholtz theory, is valid for arbitrary angles of incidence and reveals that grey solitons undergo either external or internal refraction depending on the soliton contrast parameter.doi:10.1109/caol.2010.5634248 fatcat:6i7nj6ubzvhztaawi2wbjuwnjm
