Abstract:Photonic crystals (PhC) are periodic dielectric or metallo-dielectric structures engineerd to manipulate the properties of light. Photonic crystals can be designed to e.g. slowing down light to extremely low values[1], bend light through sharp corners [2] or prevent certain frequencies light of any polarization from propagating in one or more directions [3]. PhC are therefore proposed for many applications like optical fibers [4], optical computers [5], electron accelerators [6] and free-electron lasers [7, 8] (FEL). Investigating of the behavior of a PhC usually requires measuring the transmission and reflection spectra. It is possible to derive the band structure from these measurements and hence characterize the PhC. However, as only fields outside the PhC structure are measured, no information is available about the internal field. Numerous applications would benefit from a precise knowledge about this internal field.
