Optical Sensing, Logic and Computations in Brillouin-Active Fiber Based Neural Network in Smart Structures

摘要

Nonlinear fiber optics, in the form of stimulated Brillouin scattering (sBs), has now emerged as the essential means for the construction of active optical devices used for all-optic in-line switching, channel selection, amplification, oscillation in optical communications, optical logic elements in optical computation and sensing, and a host of other applications. The controlling of sBs in optical system based smart structures leads to neural networks with multistable periodic states; create optical logic 1 or 0. It can be used for optical logic and computations and optical sensing. It is theoretically possible also to apply the multi-stability regimes as an optical memory device for encoding and decoding series and complex data transmission in optical communications systems.
