Abstract

The development of high technologies has led to the appearance of the new class of materials and physical systems with very special optical property—photonic bandgap structures. They are the two-and three-dimensional dielectric structures; quantum wells in semiconductor superlattices; copolymer multilayer structures; colloidal crystals and optical lattices. It has been shown that soliton transmission of optical pulse in resonant¹ and Kerr^2,3 nonlinear photonic bandgap (PBG) structures are possible within the Bragg frequency forbidden gap band, so-called gap solitons. We consider theoretically (1) the propagation and interaction of the gap solitons in a one- and twodimensional resonant PBG structures with inhomogeneously broadened spectral line, (2) generation and amplification of gap solitary waves in a resonant gain grating, and (3) oscillating zoomeron-like pulses interacting in a deformed PBG structure.
