"Photonic Bandgap Crystal, Flattop Narrow-Band Filter, Modulators, and Switches"
Since the concept of Photonic Bandgap Crystal (PBC) was introduced in 1989 as a means to make low lasing threshold lasers, many many more applications of PBC have been suggested, particularly in the telecommunication area. In this talk, we will discuss the R-matrix technique to calculate the transmission through a PBC and the dispersion of surface waves on a PBC. On the application side, we will discuss the design of a flattop, narrow-band, tunable filter for use in Dense Wavelength Division Multiplexing (DWDM) systems. By incorporating non-linearity, we can make an all-optical modulator or switch. A nonlinear Finite Domain Time Dependent (FDTD) technique to simulate such a device will also be presented.
