Abstract
This paper provides computed results elucidating the nature of resonant leaky modes associated with periodic refractive-index lattices such as gratings and photonic crystals. Computed Brillouin diagrams illustrate the association of the guided-mode resonance with the second stopband demonstrating the effects of grating profile symmetry and its Fourier harmonic content. Examples of wideband bandpass filters are given and the influence of variations in some of the design parameters on their spectral features is numerically evaluated. Reflectors with wide spectral and angular apertures are presented and their parametric sensitivity explored. Single-layer polarizers are demonstrated. Addition of homogeneous layers to enhance spectral features of the elements is briefly examined.
