1Cooperative interactions between nano-antennas in a high-Q cavity for unidirectional light sources显示文摘We analyse the resonant mode structure and local density of states in high-Q hybrid plasmonic-photonic resonators composed of dielectric microdisks hybridized with pairs of plasmon antennas that are systematically swept in position through the cavity mode.On the one hand,this system is a classical realization of the cooperative resonant dipole–dipole interaction through a cavity mode,as is evident through predicted and measured resonance linewidths and shifts.At the same time,our work introduces the notion of‘phased array’antenna physics into plasmonic-photonic resonators.We predict that one may construct large local density of states(LDOS)enhancements exceeding those given by a single antenna,which are‘chiral’in the sense of correlating with the unidirectional injection of fluorescence into the cavity.We report an experiment probing the resonances of silicon nitride microdisks decorated with aluminium antenna dimers.Measurements directly confirm the predicted cooperative effects of the coupled dipole antennas as a function of the antenna spacing on the hybrid mode quality factors and resonance conditions.Kevin G.Cognee Hugo M.Doeleman Philippe Lalanne A.F.Koenderink 2019Light(Science & Applications)2019,8,1:6
