چکیده
Abstract We investigated the beam profiles and polarization states in low-temperature photoluminescence from vertical GaAs/InGaAs/GaAs core-multishell nanowire (NW) under continuous-wave pulsed excitations. In profile excitation, a doughnut-shaped intensity distribution was confirmed. The shown to exhibit an axisymmetric polarization. These observations indicate that cylindrical vector beams were generated NW. observed did not correspond low-order but suggested generation of higher-order beams.

Analysis of Critical Dimensions for Nanowire Core-Multishell Heterostructures
Critical dimensions for nanowire core-multishell heterostructures are analyzed by using finite-element method based on the energy equilibrium criteria. Results show that the nanowire core-shell heterostructure can sufficiently reduce the strain in the shell and increase the critical shell thickness. The critical dimensions for the nanowire core-multishell heterostructure are determined by the s...

متن کاملDiscrete cylindrical vector beam generation from an array of optical fibers.
A novel method is presented for the beam shaping of far field intensity distributions of coherently combined fiber arrays. The fibers are arranged uniformly on the perimeter of a circle, and the linearly polarized beams of equal shape are superimposed such that the far field pattern represents an effective radially polarized vector beam, or discrete cylindrical vector (DCV) beam. The DCV beam i...

We report the growth and characterization of core/multishell nanowire radial heterostructures, and their implementation as efficient and synthetically tunable multicolor nanophotonic sources. Core/multishell nanowires were prepared by metal-organic chemical vapor deposition with an n-GaN core and InxGa1-xN/GaN/p-AlGaN/p-GaN shells, where variation of indium mole fraction is used to tune emissio...
