Abstract
A guided-wave lens is reported. The present lens structure is realized by embedding a low-index lens-shaped waveguide region in a surrounding higher-index planar waveguide. Very large index differences between the lens region and host waveguide are realizable using this technique, making it possible to fabricate low f-number lenses with low spherical aberration. The lens exhibits excellent off-axis performance, low chromatic aberration, and high polarization independence. A prototype f/2 lens in a GaAs/Ga0.97Al0.03As waveguide has been designed and fabricated using Corning 7059 glass and SiO2 for the lens waveguide structureKeywords
