Design optimization is very important to achieve high performances of integrated optical devices. For accurate designs, detailed information on the characteristics of slab and channel guides made in glass substrates must be known in relation to their fabrication conditions since these waveguides often form the basic units in more complicated waveguide structures used in devices. This paper outlines the characterization and modeling procedures of such waveguides, and presents the methodology of design optimization of waveguide devices. In particular, the beam propagation method (BPM), combined with the effective index method (EIM), is discussed. The variational technique combined with the effective index method is also discussed.
