Strong radiative coupling between two quantum emitters with arbitrary mutual orientation via a silver nano-arc

Abstract Strong radiative coupling realizes coherent exchange of single excitation between two quantum emitters, while their dipole orientation influences the coupling strength in anisotropic environments. We propose a silver nano-arc with arbitrary radian which can support two hot spots of electric field with radian-independent resonant wavelength. Two quantum emitters resonant with the cavity mode, embedded inside the two hot spots and oriented along the nano-arc axis, can realize strong radiative coupling, verified by the large splitting and anti-crossing behavior in the spectrum and the population oscillation in the time domain. All these signatures of strong radiative coupling are robust against the nano-arc’s curvature. Our work provides a flexible approach to realize strong radiative coupling between two quantum emitters with arbitrary mutual orientation and facilitates quantum information processing.

Quantitative determination of modal photon number density spectrum in arbitrary dielectric structures with a quantum emitter

Li-Heng Chen, Fengfeng Luo, Yonggui 勇贵 Gao 高

Abstract Understanding the photon number statistics of a quantum emitter (QE) interacting with complex photonic environments is fundamental to advances in quantum optics and nanophotonics. We introduce a general theoretical framework for calculating the modal photon number density spectrum (MPNDS) in arbitrary dielectric structures with an embedded two-level QE. We validate our approach by investigating a system composed of a two-level QE and a photonic crystal (PhC) slab with an L3 cavity and a waveguide, finding that the MPNDS exhibits significant changes in both waveguide and background radiative channels as the interaction between the QE and modal field transitions from weak coupling to strong coupling. We observe that the number of photons guided along the waveguide shows a strong dependence on the QE’s transition frequency and transition dipole moment, but demonstrates robustness to the transition dipole moment when the transition frequency approaches the waveguide cutoff frequency. Our work allows for the determination and tailoring of light emission characteristics across diverse radiative channels in complex photonic environments.

We study fluorescence of emitters coupled to radiation fields allowing for arbitrary interatomic spacing, dipole orientations, and spatial dimension, including the first study of two dimensions. The asymptotic analysis shows coherence increases with reduced dimension.
