Abstract
A compound waveguide device having a channel waveguide in optical proximity to an elongate waveguide propagating an optical signal therein is disclosed. The channel waveguide includes a coupling surface through which optical energy is evanescently coupled to or from the optical signal propagating in the elongate waveguide. The channel waveguide is shaped to confine distribution of the optical energy therein along axes transverse to the axis of propagation of the optical energy. Transverse diffraction of the optical energy within the channel waveguide is thereby limited. In one embodiment, the elongate waveguide is a side-polished fiber optic waveguide. Electro-optic control of the compound waveguide is disclosed, as are bandstop, bandpass and detection configurations thereof.
