Paper Abstract

Germanosilicate film waveguides have been fabricated by plasma enhanced chemical vapor deposition. In the film waveguides straight waveguides, directional couplers and a Y-splitter were written directly point to point with UV-light by focussing a 244 nm beam by a single lens. No kind of mask was used to define the structure. The propagation loss of a multi-mode UV-written waveguide has been measured to 0.3 dB/cm, which is excellent for directly written waveguides. The UV-induced change of refractive index in the written components is estimated to be between 4 (DOT) 10-3 and 6 (DOT) 10-3. This provides a highly flexible and fast method for fabrication of new waveguide components.
