Abstract

We present a far-field optical technique allowing the measurement of the dispersion relation of electromagnetic fields propagating under the light cone in photonic nanostuctures. It relies on the use of a one-dimensional grating to probe the evanescent tail of the guided field in combination with a high numerical aperture Fourier space imaging set-up. A high-resolution spectroscopy of the far-field emission diagram allows us to accurately and efficiently determine the dispersion curve and the group-index dispersion of planar photonic waveguides operating in the slow light regime.
