Polarizing holographic beam splitter on a photoresist

Optics Letters, 1995
A method to take advantage of high-spatial-frequency surface-relief gratings as polarizing beam splitters is described. The analogy between that kind of grating and a volume grating is the basis of the theoretical predictions. Results of rigorous calculations are presented. High polarizing performances are demonstrated.

Self-collimating photonic crystal polarization beam splitter

Optics Letters, 2007
We present theoretical and experimental results of a polarization splitter device that consists of a photonic crystal (PhC) slab, which exhibits a large reflection coefficient for TE and a high transmission coefficient for TM polarization. The slab is embedded in a PhC tile operating in the self-collimation mode.

Polarization-independent beam splitter

Review of Scientific Instruments, 1983
We report a new type of beam splitter capable of producing a division of light in a polarization-independent manner. Most off-axis beam splitters have a pronounced polarization dependence. An experimental device with a splitting ratio of about 7 dB varied less than ±0.1 dB as a function of incident linear polarization.

Metallized photoresist grating as polarizing beam-splitter

Diffractive Optics and Micro-Optics, 2000
We propose and demonstrate the use of a simple holographic relief photoresist grating covered with an aluminum film as a reflecting polarizing beam splitter. The polarizing effects were achieved as a result of the nonsinusoidal profile of the grating. The best parameters of the gratings for optimizing the polarizing-beam-splitting properties were found

Polarization-beam-splitter-less integrated dual-polarization coherent receiver

Optics Letters, 2014
Conventional dual-polarization coherent receivers require polarization beam splitters for either the signal or the local oscillator path. This severely hinders monolithic integration, since integrated polarization splitting devices often exhibit stringent fabrication tolerances.

Polarization‐preserving reflected beam splitter

Microwave and Optical Technology Letters, 2001
AbstractThe design of a polarization preserving reflected beam splitter (PPRBS) is presented. The PPRBS consists of a V‐shaped absorbing substrate coated with a single thin‐film layer. The PPRBS operates in the UV region. The power reflection coefficient ranges from 69 to 90% for angles of incidence ranging from 85 to 89°, respectively.

A polarizing oriented smectic beam splitter

Journal of Applied Physics, 1976
A beam of unpolarized light is shown to be split into three distinct polarized beams when it passes through the core region of a smectic liquid crystal which is oriented so that its planes form concentric cylinders. In N-p-cyanobenzylidene-p-octylozyaniline (CBOOA) the angle between two adjacent exit beams is ∼22° whereas for N-p-cyano-p-octylbiphenyl (

Polarizing Beam Splitter Of Polished Type.

SPIE Proceedings, 1989
Fibre-optic polarizing beam splitters are 2x2 port components which cross-couple efficiently one input linear polarization and transmit unaffected the orthogonal one. Such a device is useful in a variety of all-fibre-optic applications such as wavelength multiplexing / demultiplexing, polarization diversity detection schemes, and fibre Raman amplifiers.

Atom interferometry with polarizing beam splitters

Physical Review A, 1998
A special kind of atomic beam splitter using a four-level atomic system in combination with polarized light fields is demonstrated. These specific atom optical elements are used to operate an atom interferometer where the beam-splitting mechanism acts selectively on specific paths only and therefore allows for several different interferometer ...
