SUPER-PICs: Swing-UP of quantum emittER single-photon sources in Photonic Integrated Circuits (ONR White Paper Tracking Number 23-000004510)
Abstract
Quantum emitters have demonstrated significant promise as deterministic single-photon sources (SPSs) for large-scale, chip-integrated photonic quantum information systems. But there has yet to be an implementation of numerous sources on a single chip that can produce triggered, highly indistinguishable single photons at GHz rates with nearly 100% efficient coupling directly into low-loss photonic integrated circuits (PICs). The objective of this project is to develop a quantum-emitter-based SPS that will be an enabling technology for that goal, using nanophotonic geometries and excitation schemes that satisfy the design requirements: high-fidelity coherent preparation of the emitter in an excited state; enhancement of the indistinguishability of the emitted photons; and highly efficient coupling of the photons into a PIC. The coherent excitation scheme to be used is known as #Swing-UP of a quantum emittER# (SUPER). The specific scientific objectives are: (1) Determine how dispersion in single-mode waveguides affects SUPER excitation. (2) Determine how optical resonances in nanophotonic structures affect SUPER excitation. (3) Design a nanophotonic structure that suppresses scattering of SUPER excitation into the collection waveguide. The expected outcomes of the project are: (a) Realization of coherent excitation of a quantum emitter in a photonic nanostructure that does not require polarization or spatial mode filtering, allowing collection of the entire fluorescence intensity. (b) A photonic element that can be integrated into PICs, and which provides quantum light with high brightness, single-photon purity, and indistinguishability. (c) Experimental demonstration of an inversely designed photonic device made specifically for quantum emitters. (d) A model of how a nanophotonic device affects the action of SUPER excitation. The quantum photonic device produced will be scalable to a large array on a single chip, and it will be an enabling technology for the Navy#s future optical quantum information processing research. Graduate students will be trained at the National Institute of Standards and Technology NanoFab facility in semiconductor fabrication techniques, preparing them to enter the next generation quantum workforce.
