Originální abstrakt
Modal reflection, transmission and loss of deeply etched Bragg waveguide gratings were modelled by six European laboratories using independently developed 2D numerical codes based on four different methods, with very good mutual agreement. It was found that (rather weak) material dispersion of the SiO2/Si3N4 system does not significantly affect the results. The existence of lossless Floquet-Bloch modes in deeply etched gratings was confirmed. Based on reliable numerical results, the physical origin of out-of-plane losses of 1D or 2D photonic bandgap structures in slab waveguides is briefly discussed.
Český abstrakt
Byla modelována vidová odrazivost, propustnost a ztráty v hluboce leptané braggovské vlnovodné mřížce. Modelování se zúčastnilo 6 evropských pracovišť se svými, nezávisle vyvinutými, numerickými programy, které byly založeny na 4 různých metodách. Vzájemné porovnání výsledků prokázalo velmi dobrý souhlas jednotlivých metod.
