Abstract
Optical waveguide devices based on optical coupling of different modes by using a mediating mode. Such waveguide devices generally have at least two coupling regions. The first coupling region couples an output mode and the mediating mode, and the second one couples the mediating mode and an input mode that copropagates with the output mode. Under proper conditions, the energy in the input mode can be completely transferred to the output mode, without energy loss to the mediating mode.
