Optofluidic Polarization Beam Splitter
CLEO: 2015, 2015An efficient polarization beam splitter (PBS) based on a silica microcapillary is proposed and experimentally demonstrated. This PBS relies on the inherent-geometry-induced birefringence. A maximum extinction ratio of up to 25 dB is achieved.

Polarizing binary diffraction grating beam splitter
Optics Letters, 2004We report a polarizing beam splitter that uses binary phase gratings written onto a liquid-crystal spatial light modulator. These gratings produce several linearly polarized diffracted orders and a zeroth-order beam whose polarization state can be completely controlled. Experimental results are shown.

Compact terahertz wave polarizing beam splitter
Applied Optics, 2010We designed a compact terahertz (THz) wave polarizing beam splitter based on a periodic bilayer structure, which operates over a wide THz wavelength range. Within a short length (about 1 mm), this polarizing beam splitter separates THz wave TE- and TM-polarized modes into orthogonal output waveguides.

Four-port integrated polarizing beam splitter
Optics Letters, 2014In this Letter, we report on the first integrated four-port polarizing beam splitter. The device operates on the principle of mode evolution and was implemented in a silicon-on-insulator silicon photonics platform and fabricated on a 300 mm CMOS line using 193 nm optical immersion lithography.

Achromatization of Wollaston polarizing beam splitters
Optics Letters, 2011We describe the achromatization of Wollaston prisms to reduce the angular dispersion in the splitting angle. Analytical theory and ray-tracing modeling is presented. In an example application, a sixfold reduction in dispersion is achieved for wavelengths in the region 400 nm to 1.7 μm.

Non-polarizing beam splitter design
Europhysics Letters (EPL), 2004In this paper a non-polarizing beam splitter design concept is presented using anisotropic thin films. Transmittance of s- and p-polarized waves can be dealt with separately. This concept can be applied to non-polarizing beam splitter designs of single wavelength and broad-band spectrum at oblique incidence.

Angular dependence of polarizing beam-splitter cubes
Applied Optics, 1994The field-of-view dependence of polarizing beam-splitter cubes has been studied to characterize their behavior in imaging systems such as optical computers and optical correlators and in other applications that involve noncollimated light. Significant polarization aberration is present in polarizing beamsplitter cubes for two reasons: (1) the s- and p ...

Birefringent polarization-independent beam splitter
Applied Optics, 1979By adjusting both the thickness and angle of the incidence of a birefringent channeled spectrum plate, the extraordinary and ordinary reflectivities can be equalized, thereby providing a polarization-independent beam splitter.

Deep-etched sinusoidal polarizing beam splitter grating
Applied Optics, 2010A sinusoidal-shaped fused-silica grating as a highly efficient polarizing beam splitter (PBS) is investigated based on the simplified modal method. The grating structure depends mainly on the ratio of groove depth to grating period and the ratio of incident wavelength to grating period.

Reflector axicon polarization beam splitter
Microwave and Optical Technology Letters, 2000The design of a reflective axicon polarization beam splitter (APBS) for a UV light is presented. The APBS consists of an absorbing substrate coated with a single-layer thin film. Two different materials are used as a substrate for the APBS. The APBS power reflectances for the p- and s-polarizations are in the range of 87 and 97%, respectively, for both
