Abstract :
Geodesic lenses are printed into glass substrates by using pressurised nitrogen and precisely machined preforms made of synthetic graphite. Multimode film waveguides of about 50 ¿m depth are fabricated by a field-assisted silver ion exchange. The geometrical tolerances, the spot size and the losses are measured.
