Multifunctional all-dielectric nano-optical systems using collective multipole Mie resonances: toward on-chip integrated nanophotonics

摘要

We present an analysis of the optical response of a class of on-chip integrated nanophotonic systems comprising all-dielectric building-block-based multifunctional light manipulating units (LMU) integrated with quantum dot (QD) light sources. Multiple functions (such as focusing excitation light, QD emission rate enhancement, photon guidance, and lossless propagation) are simultaneously realized using the collective Mie resonances of dipole and higher-order multipole modes of the dielectric building blocks (DBBs) constituting a single structural unit, the LMU. Using an analytical formulation based on Mie theory, we demonstrate enhancement of the excitation light simultaneously with the guiding and propagation of the emitted light from a QD emitter integrated with the DBB-based LMU. The QD-DBB integrated structures can serve as basic elements for building nano-optical active circuits for optical information processing in both classical and quantum realms.
