Summary form only given. Photonic band gap (PBG) crystals have been the object of intense investigation regarding the electromagnetic wave propagation phenomena at optical frequencies. Many practical applications of these structures have been suggested, at least in one dimension, for linear and nonlinear systems. We mention the photonic band edge laser, a nonlinear optical limiter and diode, an efficient...
Summary form only given. The 1980s/1990s have witnessed an intense investigation of electromagnetic wave propagation phenomena at optical frequencies in periodic structures. These structures are usually referred to as photonic band gap (PBG) crystals. Despite the fact that most applications currently available make use of the linear properties of PBGs, the study of nonlinear dynamics has also been...
