| Abstract: | The wavefront-tilt effect in nonparallel optical waveguides is studied theoretically. A self-consistent coupled-mode formalism based on guided normal modes of the individual waveguides is developed, and the wavefront-tilt effect due to the nonparallel structures is accounted for. The wavefront-tilt caused by junctions at input and output is considered by using a mode-matching method. The power exchanged between two slab waveguides separating at an angle is investigated by an analytical solution to the coupled-mode equations |
