Abstract

Compact Luneburg-type lenses of rectangular outline as viewed from above have been made by thermal evaporation of As₂S₃ glass onto single-mode LiNbO₃:Ti waveguides shaped masks and subsequent exposure of the glass to ultraviolet light. The best lenses had speeds of f/5.5 at an aperture of 10 mm and focal spots at reduced aperture about 1.2 times the diffraction-limited size. These lenses have a field of view of at least 25° inside the waveguide.
