Abstract: An electro-optical modulating device and method that provides efficient control of the nonlinear propagation constant in an optical waveguide are featured. The electro-optical modulating device provides large wavelength tunability of the generated entangled photon pairs in real-time by using an applied external bias voltage. The electro-optical modulating device uses gate-tunable material at locations near the optical waveguide. The application of an external bias voltage creates a variable field-effect which in turn varies the optical dielectric properties of the waveguide. The result is a compact active, highly efficient wavelength-tunable integrated quantum photonic device for tunable entangled photon pair generation using an external bias voltage.
