Paper Abstract

A new family of geodesic lenses was studied, having a simplified profile of the outer rim. The new rim is expected to reduce the losses and to make the fabrication easier. Two lens prototypes were made on glass with ion exchanged waveguides. The substrates grinding and polishing was performed by a machine consisting of a lathe and a special transducer to check up the profile in real time. The maximum error with respect to the theoretical profile was 15 μm. Focal spot sizes of 15-18 μm were achieved with beam widths equal to 50% of the total lens diameter.
