title: Modal coupling analysis for integrated optical components in glass and lithium niobate.
abstract: Coupling efficiency between the fundamental modes of two different graded-index waveguides, which are fabricated in glass or lithium niobate, is calculated by numerical and variational methods. Analytical results are derived by the variational approach, which supplies a systematic method for studying the influence of modal coupling on the design of integrated optical components.
