The Bidirectional Beam Propagation Method based on the Method of Lines is proposed as an innovative and efficientalgorithm to investigate the optical properties of photonic band gap (PBG) structures.

Abstract
The Bidirectional Beam Propagation Method based on the Method of Lines is proposed as an innovative and efficientalgorithm to investigate the optical properties of photonic band gap (PBG) structures. The algorithm results arevalidated by comparison with the analytical ones obtained via the transfer matrix method. Passive, lossy and active PBGstructures can be investigated. Moreover, in order to optimize the waveguiding effect, we consider one of the two layersconstituting the periodic structure made of a three-layered waveguide having refractive index variable along thetransverse direction, thus obtaining better confining performanceI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
