An overview of the present silicon-on-insulator (SOI) waveguide technology is given and supplemented with an extensive set of theory and simulation results. Characteristics of slab-, rectangular- and ridge waveguides in SOI are explained. In particular, the number of modes and the single-mode conditions are carefully analyzed. Experimental work with straight and bent 8 to 10 μm thick SOI ridge waveguides and a very fast thermo-optical switch are reported. Propagation loss in a very long spiral waveguide down to 0.3 dB/cm, waveguide birefringence below 10-4, and a switching frequency up to 167 kHz were obtained. A very promising multi-step patterning principle for SOI waveguides is described together with many practical application examples.
