title: Experimental demonstration of 1D crossed gratings for polarization-independent high-Q filtering.
abstract: We demonstrate experimentally a spectral filter with high Q-factor (≃3238), wide accordability range (1500-1600 nm) with respect to the angle of incidence, and record polarization independence. This work is an experimental validation of the theoretical work reported in [Opt. Lett. 36, 1662 (2011)]: the filter is composed of two 1D crossed gratings engraved on each side of a planar waveguide. We provide a good comparison with theory and physical interpretations of the features observed experimentally.
