A method for controlling the nonlinear moments of a nonlinear optical material of an electrooptical device is disclosed. The method includes controlling an optical mode region of the electrooptical device by providing a time varying signal to the electrooptical device via one or more electrodes of the device and affecting the nonlinear moments of the nonlinear optical material of the electrooptical device by providing a time independent bias to the device. In one embodiment, the nonlinear optical material includes a χ 3 material. In another embodiment, the method includes employing the time independent bias to bias the χ 3 material such that the χ 3 material behaves in a manner analogous to a χ 2 material. |
