Abstract:
Based on an encoded fiber Bragg grating (FBG) array fabricated using a point-by-point femtosecond laser pulse chain inscription method, an encrypted optical fiber tag is proposed and demonstrated experimentally. A binary data sequence carried by a fiber tag can be inscribed into the fiber core in the form of an FBG array, and the tag data can be encrypted through appropriate design of the spatial distributions of the FBGs with various reflection wavelengths and reflectivities. The encrypted data are recovered via analysis of the backscattered light signal from the fiber tag. The featured grating information and the spatial distribution of the FBGs and the information carried in their specific channels can be recovered based on a code rule. The proposed fiber tag technology can be used for applications in port identification, encrypted data storage, and transmission in fiber networks.
