(a) An off-axis light-shaping task, shaping a plane wave into a uniform off-axis rectangle pattern. (b)(c) The calculated output phase gradient data, with x- and y-component respectively (Unit: 106rad/m). (d) The calculated output phase by direct numerical integration method with the gradient data (Unit: 103rad). (e) Irradiance (normalized): simulation result by field tracing, with the designed phase response function used
