| Popis: | 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. Optics: Next-generation optical sensors with unprecedented sensitivity Scientists have developed a simple technique for enhancing the properties of hybrid plasmon-photonic resonators, opening the door to micro- and nanoscale optical technologies for use in vibrational spectroscopy, lasers, and solid-state lighting devices. Optical sensors with whispering gallery mode resonators, in which light waves travel around a concave surface, possess unprecedented sensitivity and have evolved into valuable tools for probing nonlinear optical phenomena and quantum electrodynamical principles. By investigating the hybridization of microcavities with multiple metal nanoparticles, Kévin Cognée and colleagues from AMOLF and the University of Amsterdam in the Netherlands, in collaboration with researchers from the University of Bordeaux in France, have developed plasmonic-photonic resonators composed of dielectric microdisks hybridized with pairs of plasmon antennas that increase light-particle interaction strength, tailoring their emission properties. The work holds the promise of next-generation analytical and diagnostic technologies. |
