Paper Abstract

Propagation and interaction of electromagnetic waves in nonuniform Bragg grating structures with space-modulated coupling coefficient and phase shifts are investigated theoretically on the base of coupled-wave model. For gratings with antisymmetically-modulated coupling coefficient the simple analytical expression for reflectivity and transmitivity are obtained. They involve the infinite set of Born approximations and are valid not only for 'shallow' gratings with (kappa) L<<1 (kappa is coupling strength, L is grating length), but also for 'deep' gratings with appaL>=1. One the base of these expressions the method for designing the shape of Bragg grating structures, which possess the required transmission spectra, is proposed. The gratings with space- modulated amplitude and phase shifts, possessing the nearly rectangular transmission spectrum, are designed with their potential application for channel separation in high-bit- rate optical fiber communication networks.
