Characterisation of photonic crystal and nanophotonics devices with Fourier optics

We report on the experimental investigation of the Floquet-Bloch modes propagation inside photonic crystal (PhC) structures as well as their emission from the structures with far-field optics. We demonstrate that far-field optical experiments can be used to retrieve fundamental optical properties of PhC structures, Such as the light path, the dispersion Curves above and below the light cone, and the equi-frequency Surfaces both in one and two dimensions, in a single step and without numerical post-processing.
