Second Order Process

We describe a wavelength conversion experiment (generation of a pulse at the wavelength λp - Δλ from a signal at λp+Δλ under the action of a pump at λp) performed through cascaded second-order process in a lithium niobate channel waveguide. With a 58-mm-long Ti diffused channel waveguide, λp=1.1 μ m (the wavelength of phase matching for the first step of sh generation), Δλ of several nanometers and 20 ps pulse duration, wavelength conversion with unit efficiency is obtained with a pump pulse energy of the order of 102 pJ. The experimental results are successfully interpreted by making use of modal analysis and solving the appropriate nonlinear equations.

With the different sizes of the structure parameters of the SOI(Silicon on Insulator) rib waveguide, the dispersion and the nonlinearity parameters are investiaged using the beam propagation method. It is found that for the same structure parameters, the dispersion and the nonlinearity parameter γ are different between the TE and TM modes. With the changing of the structure parameters the anomalous dispersion and the nonlinearity parameter γ can be up to 972 ps/km/nm and 1.065×106w-1.km-1in the wavelength region near 1550nm.The high anomalous dispersion and the nonlinearity parameter γ means it’s a good candidate to realize parametric amplification and wavelength conversion.
