Abstract

The optical waveguide lens is an important and basic component in many integrated optical devices, performing such functions as focussing and collimating, Fourier transformation and optical signal processing. For many applications of the optical waveguide lens, diffraction-limited performance is required. Such a stringent focussing criterion necessitates careful control of the design parameters and fabrication procedure, as well as the in situ variables which may affect the lens performance. The design and performance of geodesic lenses and grating lenses have been treated in the past. However, for the mode-index lens, among which the Luneburg lens' shown in Fig. 1, is perhaps the most common, no complete examination of the fabrication tolerances has been made.
