AbstractRecent advances of glass materials and fabrication processes will be reviewed in the field of guided-wave technology. A variety of optical fibers and guided-wave devices are in development by using high-silica and non-silica glasses. Following the successful development of silica fiber, a new family of optical fibers is being investigated by using non-silica glasses such as fluoride and chalcogenide glasses, which operate at mid-infrared wavelength range and offer the potential of ultra-low loss. High-silica channel waveguides are fabricated by processing a SiO2TiO2 planer waveguide on a silicon substrate. These are applied to various guided wave optical circuits such as switch and wavelength-division multi/demultiplexer, which would be used for the construction of optical communication systems. The materials and processing techniques influencing optical guided-wave performance are described.
