By the couple-mode theory, the first order differential equations describing the propagation mode through the grating x direction are given by Eqs. (4), (5). (4)dR(x)dx=iσ̂R(x)+iκS(x)(5)ddS(x)ddx=iσ̂S(x)+iκR(x). The parameter R(x) and S(x) are the amplitudes...
Optical fiber grating sensors in multimode fibers We present a novel class of optical fiber sensors based on fiber Bragg gratings written in germanium-doped silica multimode fibers that can be implemented ... Z Wei,RO Claus - Spies International Symposium on Smart Structures & Materials 被引量:...
Bragg grating Encyclopedia n. A diffraction grating created within the structure of a substance, especially an optical fiber, by periodically varying the index of refraction in successive layers within the substance, causing certain frequencies of light passing through the substance to be reflected away...
The method is designed to solve the twisted PM-FBG simulation. The four mode matrix element of a period grating is derived from the S matrix element and the method only involves the torsion-induced shear strain entry e x y which can be considered as the rotation of the principal axis of ...
