Paper Abstract

There is a strong need for the development of cheap component technologies for optical functions such as switching, demultiplexing and amplification. Silica-on-silicon integrated optics using sol-gel processing is probably the best technology for such low cost applications. This review focuses on the sol-gel based thin film fabrication technologies for integrated optics (IO) lasers and amplifiers, using Nd3+ and Er3+ as the active species. Special emphasis is given to the work performed under the European Union sponsored projects NODES (ESPRIT) and CAPITAL (ACTS), in particular to the processing and characterization of Nd3+ and Er3+-doped silica-titania planar waveguides for IO lasers and amplifiers.
