Abstract

We have observed the Fano-type Faraday rotation spectrum in a one-dimensional magnetophotonic crystal at the Bloch surface wave (BSW) resonance and found that it is a result of the coupling between the $s$ -polarized BSW and the $p$ -polarized waveguiding modes of the magnetophotonic crystal. The shape of the resonance is determined by the relative position and spectral splitting of the modes.
