	The state of the art for liquid crystal adaptive optics in astronomical applications (EI CONFERENCE) 会议论文 OAI收割 2012 International Conference on Optoelectronics and Microelectronics, ICOM 2012, August 23, 2012 - August 25, 2012, Changchun, China 作者: Liu Y.; Liu Y.; Xuan L.; Liu Y. 收藏 \| 浏览/下载：26/0 \| 提交时间：2013/03/25 In this paper we summarize the researches of liquid crystal (LC) adaptive optics(AO) in astronomical applications. Dual frequency and nematic LC materials were reported to be used in astronomical observations. However nematic LC with its simple producing and driving method and multi-gray-level is promising in the application. We have investigated the nematic LC AO system and promoted its application for nearly ten years. Here we reported our newest nematic LC AO system with bandwidth result of 3dB is 54.4 Hz 0dB bandwidth is 79.1Hz. 2012 IEEE.

	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：33/0 \| 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.
