中文摘要： 本申请研究基于半导体的光逻辑门在运算速率突破100Gb/s时潜在的物理限制性因素，并实现100Gb/s速率下的逻辑操作。提出一种基于电吸收调制(EAM)中交叉吸收调制(XAM)效应以及半导体光放大器（SOA）中自相位调制（SPM）原理的可重构光逻辑门，可以实现AND、OR、NOT逻辑运算，将利用半导体混合集成的工艺将其制作成通用光逻辑门芯片。本申请还提出了高速可重构光全逻辑门概念，不仅可以实现任意二元逻辑运算，而且逻辑功能转换可以达到与逻辑运算本身相同的速率。将利用SOA中的交叉增益调制（XGM）效应以及EAM中的XAM效应实现这种光逻辑门。通过对光逻辑门高速化、芯片化、可重构化方向上的一系列研究工作，推动光逻辑门的基础研究和实际应用。

英文摘要： In this proposal, we study the physical factors which could potentially limit the performance of semiconductor based optical logic gate when the operating speed is beyond 100 Gb/s. 100-Gb/s logic operation will be demonstrated. A reconfigurable optical logic gate is proposed with AND, OR, NOT logic operations based on the cross absorption modulation (XAM) effect in an electroabsorption modulator (EAM) and self phase modulation (SPM) effect in a semiconductor optical amplifier (SOA). A corresponding optical logic gate chip will be implemented with optical hybrid integration method. We also advocate the concept of high-speed reconfigurable optical all-logic gate which is capable of every possible binary logics. The logic reconfiguration speed can be made as high as the logic operation itself. A realization of the high-speed reconfigurable optical all-logic gate will be demonstrated by utilizing the cross gain modulation (XGM) effect in SOAs and XAM effect in an EAM. We anticipate pushing forward the basic research as well as real applications of optical logic gates with the combined effects in the integration, reconfigurable design and high speed operation studies.
