Geodesic optics: new components

In integrated optics, geodesic lenses show some peculiar characteristics that have attracted increasing attention. Such properties also suggested the realization of components other than lenses, that is, of geodesic elements capable of performing operations different from focusing. In this paper we present a new class of geodesic components able to steer, deflect, or spread a guided beam. Such components have been designed following the same analytical procedure. They have no connection apart from the vertex in some cases. A first geodesic corner reflector has been realized in the laboratory. Some preliminary results are shown and discussed.
