Generation 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 کاملGenerating Radially and Azimuthally Polarized Beams by Using a Pair of Lateral Displacement Beamsplitters
This paper proposes a modified polarization converter for generating radially and azimuthally polarized beams. Based on a Mach–Zehnder-like interferometric structure, the device consists of a pair of lateral displacement beamsplitters (LDBs) and two half-wave plates that manipulate the states of polarization of incident linearly polarized light. Through the coherent superposition of two orthogo...
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 کاملSubwavelength Gratings for Generating Azimuthally Polarized Beams
We have experimentally investigated two binary subwavelength grating-miсropolarizers that transform linearly polarized light to the azimuthally polarized beam. The first miсropolarizer operates in reflective mode (for wavelength 532 nm) and was manufactured in a gold film. The second micropolarizer operates in transmitting mode (for wavelength 633 nm) and was manufactured in silicon.
متن کاملWhite light Bessel-like beams generated by miniature all-fiber device.
Micron-sized white light propagation invariant beams generated by a simple and compact fiber device are presented. The all-fiber device is fabricated by splicing a short piece of large-core multimode fiber onto a small-core single mode white light delivery fiber. Because this fiber device offers an inherent spatial coherence, nondiffracting white light beams can be created with a temporally inc...
