Addressable Surface-Curvature Driven Mesa Top Single Quantum Dot Based Single Photon Source Array Integrated On-Chip with Dielectric Light Manipulating Elements

Abstract

This proposal seeks support for a path-breaking, novel, and realistic program focused on pushing the frontiers of on-chip integrated optical nanophotonic systems suitable for operation in the many(classical), few, and single (quantum) photon regimes aimed at quantum information processing (QIP). It is well recognized that such systems require spatially ordered (addressable) and spectrally uniform single photon sources (SPSs), integrated on-chip with co-designed light manipulating elements that provide the required multiple functions of emission rate enhancement, emitted photon guidance, and lossless propagation, etc.. Towards this end, we will pursue a new paradigm for realizing spatially regular arrays of size and shape controlled single quantum dots that, we have shown, act as single optical photon emitters and can be readily integrated on-chip with co-designed subwavelength size dielectric building block (DBB) based architectures whose collective Mie resonances (primarily magnetic) provide the needed multiple light manipulation functions such as enhancement of SQD emission rate (Purcell effect), directing and guiding the emitted photons (nanoantenna-waveguide), and beam splitting. On such arrays, following the overgrowth of a suitable planarizing overlayer, we will fabricate the above noted light manipulating elements utilizing the newly emerging approach of exploiting the collective Mie resonances of subwavelength dielectric building blocks and / or the well-established 2D photonic crystal platform to implement the desired light manipulating functions. To achieve these objectives, the current opticalmeasurement instrumentation will be enhanced with the requested equipment to characterize the optical response of the fabricated SQD array without and with interfacing to DBB light manipulating units.
