  • Resonantly coupled waveguides using a taper
    Patent number: 6310995
    Abstract: A resonant coupler has a coupling region having first and second ends, a coupling length, and a tapered variable width, such that a phase matching condition for the waveguide is met within the coupling length. In an exemplary embodiment the first and second ends each have a corresponding variable width which varies at a rate greater than the variable width of the coupling length. In yet another embodiment the coupling region has an electrically sensitive phase matching characteristic and an electrode in operative relation with the coupling region for varying the phase matching characteristic.
