Abstract

We extend the recently developed NARP scheme for laser-triggered single photon emitters to enable simultaneous excitation of multiple channels for wavelength-division multiplexing in quantum networks.

Multi-NARP laser driving scheme for multiplexed quantum networks

We extend the recently developed Notch-filtered Adiabatic Rapid Passage (NARP) scheme for laser-triggered single-photon sources to the simultaneous excitation of multiple emitters with varying transition energies, laying the groundwork for wavelength-division multiplexing in quantum optical networks. Our multi-NARP scheme does not rely on polarization filtering and thus enables the near-unity extraction efficiency of single photons from each quantum dot. Our approach also offers the advantages of robustness to variations in the laser pulse parameters and immunity to excitation-induced dephasing tied to electron–phonon coupling. We show that simultaneous triggering of at least 10 emitters is possible, enabling the development of high-bandwidth quantum networks.

We report the application of chirped laser pulses to the simultaneous triggering of more than 10 semiconductor quantum dots with optical transitions spanning 15 meV using a single laser pulse and adiabatic rapid passage (ARP), laying the foundation for wavelength division multiplexing schemes. In conjunction with the application of Notch-filtered Adiabatic Rapid Passage (NARP) [9], our work will support the development of high-performance, scalable quantum photonic systems.

In this presentation I will describe a new laser driving scheme for triggered high-brightness single photon emitters using a chirped laser pulse possessing a spectral hole resonant with the transition energy of the emitter, referred to as Notch-filtered adiabatic rapid passage (NARP). When combined with optimized photonic structures for enhanced collection efficiency and commercial filters we estimate that NARP would provide less than 10-8 scattered photons per emitted photon with a 4% detection loss together with resonant driving for high photon indistinguishability. We demonstrate inversion using NARP experimentally in a single semiconductor QD.
