Generating 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 and azimuthally polarized nonparaxial Bessel beams made simple.
We present a method for the realization of radially and azimuthally polarized nonparaxial Bessel beams in a rigorous but simple manner. This result is achieved by using the concept of Hertz vector potential to generate exact vector solutions of Maxwell's equations from scalar Bessel beams. The scalar part of the Hertz potential is built by analogy with the paraxial case as a linear combination ...
متن کاملRadially and azimuthally polarized nanosecond Yb-doped fiber MOPA system incorporating temporal shaping.
We report an Yb-doped fiber master-oscillator power-amplifier (MOPA) system with the capability of selectively generating doughnut-shaped radially and azimuthally polarized beams with user-defined temporal pulse shapes. The desired output polarization was generated with the aid of a nanograting spatially variant half-waveplate (S-waveplate). The latter was used to convert the linearly polarized...
متن کاملWaveguide properties of single subwavelength holes demonstrated with radially and azimuthally polarized light
We investigate the transmission of focused beams through single subwavelength holes in a silver film. We use radially and azimuthally polarized light, respectively, to excite higher order waveguide modes as well as to match the radial symmetry of the aperture geometry. Remarkably, the transmission properties can be described by a classical waveguide model even for thicknesses of the silver film...
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.
