(a) Efficiency and uniformity of simulated diffraction gratings for 7 planes generation as a function of the binary step phase-shift. Vertical lines positions: plain: π, dashed: 0.95 × π, dotted: 0.86 × π. (b) The physical shape obtained for the 0.95 × π phase shift (c) the corresponding diffraction pattern, (d) the wavelength dependency of the efficiency and uniformity showing dual bands at 612 nm and 670 nm. (e) The physical shape obtained for the 0.86 × π phase shift, (f) the corresponding diffraction pattern, (g) the wavelength dependency of the efficiency and uniformity showing dual bands at 514 nm and 670 nm.
