Paper Abstract

The design principles are presented for a new class of homogeneous thin-film waveguide lens. The lenses consist of many lens elements with circular boundaries and are amenable to conventional photolithographic methods of manufacture. The design gives very low spherical aberration for axial input beams with apertures up to f/3. By modifying the lens effective refractive index the focusing performance can approach the diffraction limit for input angles up to 8° from the axis.
