Abstract
Interaction of electromagnetic guided modes with index/gain Bragg gratings in step-index round optical fibers is considered theoretically. The analysis includes the construction of exact solution of Maxwell equations in core and cladding regions, which strictly obeys the electromagnetic boundary conditions on core/cladding interface and on Bragg grating boundaries. The grating profiles, for which the exact solutions of Maxwell equations can be expressed in the closed analytical form, are determined and the corresponding expressions for scattered electromagnetic fields are presented. The constructed solution enlarges the class of exactly solvable diffraction problems. It can be used to examine and to control numerical theories of light propagation and scattering optical fibers with intracore Bragg gratings.
