Numerical Analyses of the Polarization Dependent Cladding Mode Coupling in Localized Fiber Bragg Gratings

IEEE Access, 2021
The polarization dependence of cladding mode coupling in fiber Bragg grating (FBG) plays a significant role in the excitation of surface plasmon resonances (SPR) for sensing applications.

Azimuthally polarized cathodoluminescence from InP nanowires [PDF]

Applied Physics Letters, 2015
We determine the angle and polarization dependent emission from 1.75 µm and 2.50 µm long InP nanowires by using cathodoluminescence polarimetry. We excite the vertical wires using a 5 keV electron beam, and find that the 880 nm bandgap emission shows azimuthally polarized rings, with the number of rings depending on the wire height. The data agree well

Minimal Focal Spot Size Measured Based on Intensity and Power Flow

Sensors, 2021
It is shown, theoretically and numerically, that the distributions of the longitudinal energy flow for tightly focused light with circular and linear polarization are the same, and that the spot has circular symmetry.

A Circularly Polarized Parallel Plate Waveguide Lens-Like Multiple-Beam Linear Array Antenna for Satcom Applications

IEEE Access, 2023
This work presents a full metal circularly-polarized lens-like antenna for Satcom applications at Ka-band. The antenna is composed of two continuous parallel plate waveguide (PPW) quasi-optical beamformers (QOBF), feeding an array of septum polarizers to

Fiber based polarization filter for radially and azimuthally polarized light

Optics Express, 2011
We demonstrate a new fiber based concept to filter azimuthally or radially polarized light. This concept is based on the lifting of the modal degeneracy that takes place in high numerical aperture fibers. In such fibers, the radially and azimuthally polarized modes can be spectrally separated using a fiber Bragg grating.
