We investigated a possibility of making rutile TiO 2 channel waveguides for nonlinear optical applications. Single mode conditions, the group velocity dispersion and the nonlinear-optical parameters for the rutile TiO 2 channel waveguides were calcul

We present a fabrication procedure for ZnO channel waveguides intended for nonlinear optical applications. Ar ion milling was used to etch the single crystal thin film samples, and the effects of bias power, chamber pressure and Ar flow rate were inv

We describe a phase-matching scheme for generating the second harmonic in ZnO channel waveguides using a modal phase-matching (MPM) method. We found that MPM can be achieved between the TM00 mode of the fundamental wave and the TM02 mode of the secon

In this paper, we analyze the nonlinear optical parameter γ estimated from experimental results of spectral broadening in ZnO channel waveguides. The effective area was calculated for waveguides of various dimensions and using the resulting data, th

We report the observation of nonlinear optical effects in the visible spectrum using ZnO channel waveguides. We demonstrate sixfold spectral broadening and a 2π phase shift due to self-phase modulation in ZnO channel waveguides using femtosecond opt

ZnO channel waveguides were fabricated for the first time, for the purpose of being used in nonlinear optical applications. Wide-bandgap ZnO was chosen for the core material to avoid two-photon absorption at wavelengths above 800 nm which are used fo
