Abstract

We have found an efficient approximation based on a quasi-mode method to analyze radiation-mode coupling in long-period fiber grating devices, and which was deduced by consideration of the best confinement condition of radiation-mode spectra inside an optical fiber. A single-mode representation via the quasi-mode method enables one to solve the radiation-mode-coupling problems analytically, which is the advantage of the method. The numerical accuracy is found to quite acceptable in comparison with the conventional method of the Green-function representation of radiation-modes via numerical computation of the integral. Utilizing the proposed method, we present several numerical examples for radiation-mode coupling problems both in uniform and non-uniform LPFGs.
