A method and apparatus for implementing optical radio frequency reconfigurable optical logic gates

Abstract

The application discloses a kind of method and device for realizing optical carrier radio frequency reconfigurable optical logic gate, can be realized in the logic gate operation in optical carrier radio frequency system, and simultaneously realize millimeter wave signal generation.Optical carrier radio frequency signal processing technology can realize the change processing of information in optical fiber and wireless channel, with high-speed information processing capability.The present application fills in the blank of optical logic gate in optical carrier wireless communication system based on the scheme for realizing optical logic gate, and then the spectrum can be expanded to millimeter wave band, terahertz band, with simple structure, low cost, reconfigurable and many other advantages, in addition, with the development of integrated photonics, more and more basic devices such as modulator, photodetector and interconnection device can obtain satisfactory performance.In addition, the exclusive or (XOR) logic gate realized by the present application has the advantages of high extinction ratio and good signal quality, which is very suitable for application in secure communication system, and has great research potential.
