It was based on the fact that in the asymptotic limit, Bessel functions essentially resemble the plane waves with an additional amplitude factor of r in its denominator. In this method, the field in the core of the Bragg fiber and up to a certain finite number of cladding layers (say N1...
Optimal performance occurs at a 10 m offset, exhibiting a maximum group delay of 35 ps and a derived slow-down factor (SDF) of up to 1.54, with a 12.5 dB transmission dip and a propagation loss of 1.16 dB/cm, in vertical polarization. The experimental SDF results demonstrate the ...
The linear relationship existing between the deformation and the wavelength shift can be calibrated to obtain a gauge factor. In a calibration test applied individually to each FBG, the fiber with the FBG was subjected to an incrementally increased tensile load using dead weights, and the ...

(12)fi=∫dVnir→−r→ie−iG→⋅r→−r→i Consequently, the atomic scattering factor fi increases with increasing atomic number Z, so that heavy atoms give more intense Bragg reflections in X-ray diffraction patterns. On the other hand bi does not vary monotonously with Z and the re...
O, entrance plateau; P, preproximal peak; Q, proximal peak; R, midpeak; S, distal peak; T, cross-fired peak. The single-port Bragg curve is shown at the top of the panel, and two overlapping parallel-opposed single-port beams are illustrated in the middle of the panel [in which ...
