Abstract

The influence of beam convergence on the photonic band- gaps, or stop-bands (SBs), of one-dimensional photonic crystals (1D PCs) is investigated. The investigation is based on an analysis of the gap map obtained from refiection spectra, calculated by the transfer matrix method for various angles of light incidence, ', and polarisations. The calculated data is compared with refiection spectra taken using Fourier Transform Infrared microspectroscopy. It was found that the introduction of the parameter, Δφto account for the focused light beam, for angles up to 20°, has little effect on the first, or lowest SB and the SBs adjacent to it. However, an increase in the order of the SB causes an increase in the infiuence of this parameter.
