| 摘 要： | 基于在细菌视紫红质膜中的自衍射，我们提出了全光非、异或、半加器及同或门逻辑操作。利用衍射光与记录光偏振状态之间的关系，我们演示了非门和同或门逻辑操作。 通过衍射光，记录光和读出光之间的偏振状态的关系，我们实现了异或逻辑操作和具有三个输入端的半加器逻辑操作。所用方法简单实用。

| Abstract: | Based on self-diffraction in bacteriorhodopsin (bR) film, we propose all-optical NOT, XOR, half adder and XNOR logic operations. Using the relation between diffraction light and the polarization states of recording beams, we demonstrate NOT and XNOR logic operations. Studying the relation of polarization states among the diffracting, recording and reading beams,we implement XOR logic and half adder operations with three inputs. The methods are simple and practicable. |
