Abstract
A method includes transmitting a sequence of wavefronts of the optical carrier wave having a first wavelength to an optical waveguide and transmitting a control wave having a second wavelength to a control waveguide. The control wave electro-optically modulates velocities of the wavefronts in the optical waveguide. A dielectric cladding adjacent the optical waveguide has a refractive index at the second wavelength that is larger than the refractive index in the optical waveguide at the first wavelength.
