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.

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.

Gratings in the resonance domain as polarizing beam splitters
Optics Letters, 1995Polarization-selective gratings in the resonance domain of diffractive optics are calculated by use of rigorous electromagnetic diffraction theory. The polarizing effects are attained by special surface-relief structures, and the profile of binary surface-relief gratings is optimized with a nonlinear Newton algorithm to design diffractive polarizing ...

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 ...

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.

Study of the injection molding of a polarizing beam splitter
Applied Optics, 2006We describe the replication of a relief grating that behaves like a polarizing beam splitter by injection molding. Measurements of the grating master, nickel shim, and replica, performed by atomic force microscopy, allow establishing a limit for the injection molding technique (currently used in CD fabrication) to aspect ratios of approximately 0.15 ...

Polarization-independent beam splitter
Review of Scientific Instruments, 1983We 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.

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.
