英文摘要	Convex cylindrical lens and concave cylindrical mirror using 2D non-periodic high-index contrast gratings (HCGs) by introducing a parabolic cylinder phase front are proposed and numerically investigated, simulation results indicate that the transmitted or reflected light beam of the structures can be modulated by the grating blocks and will converge into a line of light or a linear spot on the image plane while maintaining high transmissivity or reflectivity with low polarization dependence. An HCG convex cylindrical lens sample with a focal length of 250 μm and a grating area of 400 μm × 400 μm are fabricated on an SOI wafer, which exhibits a liner focusing ability on the image side under normal incidence at the wavelength of 1.55 μm. © 2020 The Japan Society of Applied Physics.
