Are Bragg Peaks Gaussian?
It is common practice to assume that Bragg scattering peaks have Gaussian shape. The Gaussian shape function is used to perform most instrumental smearing corrections. Using Monte Carlo ray tracing simulation, the resolution of a realistic small-angle neutron scattering (SANS) instrument is generated reliably. Including a single-crystal sample with large d-spacing, Bragg peaks are produced. Bra...
متن کاملTopological Bragg Peaks and How They Characterise Point Sets
Bragg peaks in point set diffraction show up as eigenvalues of a dynamical system. Topological Bragg peaks arrise from topological eigenvalues and determine the torus parametrisation of the point set. We will discuss how qualitative properties of the torus parametrisation characterise the point set.
متن کاملInverse-Gaussian apodized fiber Bragg grating for dual-wavelength lasing.
A fiber Bragg grating (FBG) with an inverse-Gaussian apodization function is proposed and fabricated. It is shown that such a FBG possesses dual-wavelength narrow transmission peaks and the wavelength spacing between the two peaks is easily controllable during fabrication. Incorporating such a FBG filter into a fiber laser with a linear cavity, we obtain stable dual-wavelength emission with 0.1...
متن کاملDesign of Gaussian Apodized Fiber Bragg Grating and its applications
In this paper,The Gaussian Apodization technique is used to design of apodized Fiber Bragg Grating.The effect of apodization on switching of FBG are studied and it can be seen that by changing the parameter of Gausian Parameter the slope of curve change.This paper also deal with design of optimized slope for optimum switching.Simulation result is found with the help of AOS softwrae.application ...
متن کاملEnhancing optical field intensities in Gaussian-profile fiber Bragg gratings.
Gaussian profile fiber Bragg gratings exhibit narrow-bandwidth transmission peaks with significant group delay at the edge of their photonic bandgap. We demonstrate group delays ranging from 0.2 to 5.6 ns from a 1.2 cm structure. Simulations suggest such a device would be capable of enhancing the field intensity of incoming light by a factor of 800. Enhancement is confirmed by photothermally in...
