Integrated Quantum Networks of Mie-resonance based All-Dielectric Optical Circuits with Single Photon Sources for Quantum Entanglement

Recently we introduced [1] a new approach to on-chip optical circuits based on subwavelength scale dielectric building blocks (DBBs) metastructures integrated with single photon sources (SPSs) such as the mesa-top single quantum dot (MTSQD) ordered array [1] in which a single collective Mie resonance of the DBB metastructure provides all needed five light manipulating functions [2]: (1) SPS emission rate enhancement, (2) emission directionality, (3) wave-guiding (4) beam-splitting and (4) beam-combining. The simulations reported were for spherical DBBs as it enables analytical calculations [1]. The lithographic fabrication of such structures will have rectangular DBBs and thus in this talk we present the design and simulation of networks of rectangular DBBs, co-designed for monolithic integration with GaAs/InGaAs MTSQD SPS arrays such that every MTSQD is coupled to the same single collective mode of the network. Finite element based simulation results for such networks with coupled SPSs will be presented that suggest quantum effects such as path-entanglement and super-radiance– constituting a step towards quantum information processing.
