	Using one-dimensional nonlinear photonic crystal for dynamical addressing optical interconnection (EI CONFERENCE) 会议论文 OAI收割 ICO20: Optical Information Processing, August 21, 2005 - August 26, 2005, Changchun, China 作者: Li C.; Wang W.; Wang W.; Li C.; Li C. 收藏 \| 浏览/下载：35/0 \| 提交时间：2013/03/25 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.
