We determined the optical constants (the refractive index n and the extinction coefficient k) of ion beam sputter deposited zirconia thin films with spectroscopic ellipsometry (SE). First  we obtained the structure information (the layer thickness  surface roughness and layer diffusion) by fitting the grazing x-ray reflection (GXRR) spectra. The fitted surface roughness is verified by atomic force micrometer (AFM) measurement. Second  based on the acquired structure information  the measured ellipsometry spectra are fitted in the range of 240-800nm at an incident angle of 70.25 degree. The optical constants are solved based on the Tauc-Lorentz dispersion. The optical band gap extracted by SE is 4.79eV. Finally  the optical band gap is verified by Taue plot method  which is well consistent with that of SE.

Optical interconnection is the key technique of high-speed optical information process and optical communication. A lot of approaches for optical interconnection have been proposed since Goodman in Stanford University firstly proposed the optical interconnection for very large scale integrated circuits technology. A dynamical addressing device for optical interconnection was designed and fabricated in this paper. This optical device is based on one-dimensional nonlinear photonic crystal made on the planar waveguide. The nonlinear materials ZnS and ZnSe  which have large nonlinear refractive index coefficients  were alternately deposited on the waveguide to form one-dimensional photonic crystal. The Bragg condition is changed when the input power of the control light increased due to the nonlinear characters of the materials  thus the reflective angle of the signal light can be changed with the input power change of the control light. In our experiment  when increasing the power density of control light from 0 to 2.60X105W/cm 2  the angle of the signal beam can be changed about 20. The interconnection characteristics were investigated in theory and in experiment. The testing data agree well with theoretical predictions. This kind of devices is promising to use in the all-optical interconnection  optical information processing and optical communication.
