细菌视紫红质用于光子逻辑门的研究

PHOTONIC LOGIC GATES BASED ON BACTERIORHODOPSIN

本文对基于细菌视紫红质变种材料 D96N的三种基本光逻辑操作进行了研究 .随着入射黄光强度的增加 ,菌紫质对黄光的吸收呈饱和吸收特性 ,此时紫光的照射将会使此饱和吸收阈值增加 .在黄光和紫光对样品的共同作用下 ,透射光强度会被调制 ,调制的程度取决于这两束光的相对强度以及被调制光波长 .通过观测被调制的 52 5nm检测光强度 ,我们模拟了几种基本的光子逻辑运算 :“非”、“或”和“与”运算 .

In this paper it is presented 3 photonic logic gate models based on bacteriorhodopsin polymer made from variant D96N.With the increasing intensity of yellow illumination,BR shows saturated absorption property.The illumination of purple light will make the threshold of the saturated absorption higher and change the absorption spectrum.NOT,AND and OR gate are implemented by detecting the intensity of probe light which can be modulated lower or higher by illumination of violet and yellow light on BR film,determined by their relative intensity of the two wavelength and wavelength of probe light.
