Abstract

Stepped switched optical directional couplers with sections of unequal lengths are studied. The switching diagrams for two- and three-section directional couplers were obtained. The concepts of "quasi-bar" or "quasi-cross" states are introduced for couplers with unequal sectional lengths. Loci tracing these quasi states and contours corresponding to different cross-talk levels are obtained. These curves are useful in estimating of the cross talk level due to fabrication errors.
