Abstract

An analysis is presented that describes minimization of overall channel waveguide length in integrated optical circuits incorporating directional couplers and curved sections. Calculations are presented for LiNbO₃, GaAlAs, and SiO₂-Si based optical channel waveguides. The results demonstrate the presence of a minimum total length corresponding to a particular degree of field confinement. The value of overall length at the minimum is shown to be significantly lower than that for other values of field confinement allowing single-mode operation
