Optical wavelength shifting of 1.054-nm laser pulses in excess of ±10 wavenumbers (±300 GHz) was demonstrated. The wavelength shifter consists of synchronous microwave and optical waveguides fabricated monolithically on LiNbO3. An optical pulse experiences a constant refractive index gradient that travels with the pulse and causes the wavelength shift.
