The influence of photonic crystal parameters on the photonic band-gaps

摘要

The influence of the geometrical and physical parameters on the photonic band-gap of GaAs and AlGaAs 2D photonic crystals has been investigated. As a result the gap-maps for geometrical parameters appropriate for operation at around the λ = 1.5μm wavelength have been obtained, i.e. the wavelength region most widely used in current fibre-optic telecommunications. Using these gap-maps, it is possible to find the PhC parameters for which the PhC exhibits a PBG within the telecommunication range.
