Reflection and Transmission from finite Photonic Crystal structures — •Marcus Diem, Antonio Garcia-Martin, Suresh Pereira, and Kurt Busch — Institut für Theorie der Kondensierten Materie, Universität Karlsruhe, 76128 Karlsruhe

We have implemented a scattering matrix approach for calculation of reflection and transmission properties of finite-sized Photonic Crystal samples [1]. As compared to standard transfer matrix calculations, this approach does not suffer from numerical instabilities that originate in the evanescent behavior of higher-order Fourier modes along the direction of the sample surface. As a consequence, this approach may be utilized to interpret reflection and transmission measurements on Photonic Crystals and allows a characterization of the quality of Photonic Crystals samples.
