Caption

(a)-(b) Measured time-resolved band structure readout from the drop-port output of the excited ring, which exhibits intensity projections of the band onto superpositions of different resonant modes. (c) Experimentally resolved resonant mode spectra as a function of frequency detuning and (d) the corresponding mode distributions of two selected input frequencies located at the flat and dispersive bands, respectively. (e)-(f) Observations of flat to non-flat band transitions achieved by adding long-range couplings.
