Creation of Sub-diffraction Longitudinally Polarized Spot by Focusing Radially Polarized Light with Binary Phase Lens
The generation of a sub-diffraction longitudinally polarized spot is of great interest in various applications, such as optical tweezers, super-resolution microscopy, high-resolution Raman spectroscopy, and high-density optical data storage. Many theoretical investigations have been conducted into the tight focusing of a longitudinally polarized spot with high-numerical-aperture aplanatic lense...
متن کاملRadially polarized conical beam from an embedded etched fiber.
We propose a method for producing a conical beam based on the lateral refraction of the TM(01) mode from a two-mode fiber after chemical etching of the cladding, and for controlling its radial polarization. The whole power of the guided mode is transferred to the refracted beam with low diffraction. Polarization control by a series of azimuthal detectors and a stress controller affords the tran...
متن کاملSelf-focusing of circularly polarized beams.
We present a systematic study of propagation of circularly polarized beams in a Kerr medium. In contrast to previous studies, vectorial effects (i.e., coupling to the axial component of the electric field and the grad-div term) and nonparaxiality are not neglected in the derivation. This leads to a system of equations that takes into account nonparaxiality, vectorial effects, and coupling to th...
متن کاملGeneration of radially polarized beams with an image-rotating resonator.
We show how a passive image-rotating optical resonator can be used to convert a linearly polarised, lowest-order Gaussian beam into a radially polarized beam. The image and polarization rotation of the cavity removes the frequency degeneracy of the modes, making it possible to select the radially polarized mode by cavity tuning. With the addition of gain, the same cavity should operate as a rad...
متن کاملA Single Grating-lens Focusing Two Orthogonally Polarized Beams in Opposite Direction
This paper proposes a novel high-contrast grating (HCG) element that simultaneously has two distinct functions; focusing and polarizing. The phase front distribution of a diffracted wave is fitted to that of an ideal conventional lens through properly controlling only the thicknesses of each grating bar. Finally, it is confirmed that the properly designed HCG can be a polarizer as well as a len...
