Abstract :
Summary form only given. Recently, we have reported a new type of propagation mechanism in which photons move along the localized coupled-cavity modes. Moreover, it was observed that the group velocity tends towards to zero and photon lifetime increases drastically at the coupled-cavity band edges. In the work, we experimentally demonstrate the modification of spontaneous emission from the hydrogenated amorphous silicon nitride layers in a coupled-microcavity (CMC) structure.
