Journal ArticleDOI
Finite-element modeling of spontaneous emission of a quantum emitter at nanoscale proximity to plasmonic waveguides
TL;DR: In this paper, a self-consistent finite-element method was developed to quantitatively study spontaneous emission from emitters in nanoscale proximity of plasmonic waveguides.
Journal ArticleDOI
Scanning emitter lifetime imaging microscopy for spontaneous emission control.
TL;DR: An experimental technique to map and exploit the local density of optical states of arbitrary planar nanophotonic structures by nanopositioning, which shows that the decay rate of a pointlike source of fluorescence can be reversibly and repeatedly changed by a factor of 2.
Journal ArticleDOI
Propagation of laser array beams in a turbulent atmosphere
TL;DR: In this article, the average irradiance of phase-locked and non-phase-locked radial and rectangular laser array beams is derived through vector integration and tensor operation, and the irradiance properties of these laser arrays in a turbulent atmosphere are studied numerically.
Journal ArticleDOI
Scintillation index of elliptical Gaussian beam in turbulent atmosphere
TL;DR: It is interesting to find that the scintillation index of an EGB can be smaller than that of a circular Gaussian beam in a weakly turbulent atmosphere under certain conditions and is closely related to the ratio of the beam waist size along the long axis to that along the short axis of the EGB.
Journal ArticleDOI
Singularities and Poincaré Indices of Electromagnetic Multipoles.
Weijin Chen,Yuntian Chen,Wei Liu +2 more
TL;DR: In this paper, the authors show that the index sum over the entire momentum sphere is always 2, consistent with the Poincare-Hopf theorem, and attribute the formation of bound states in the continuum to the overlapping of multipolar singularities with open radiation channels.
