A Broadband Linearly Polarized Beam-splitter
2019 IEEE International Conference on Computational Electromagnetics (ICCEM), 2019A broadband electromagnetic beam-splitting metasurface is designed and presented in this paper. This metasurface is composed of two metallic E-shaped patches modeled on FR4 dielectric substrate. The electromagnetic wave when normally incident on the proposed metasurface, it is split into two waves; half of the energy is reflected and the other half is ...

Properties of holographic polarization beam splitters
Optical Society of America Annual Meeting, 1992Many important photosensitive holographic materials used to form phase holograms are absorptive, which leads to variations in the average index and index modulation. The effect of such variations on the polarization properties of holographic optical elements is shown theoretically by using rigorous coupled wave theory and are compared to experimental ...

Design of MacNeille Polarizing Beam Splitter
2009 Symposium on Photonics and Optoelectronics, 2009MacNeille polarizing beam splitters(PBSs) has become important optical components in many optical systems. The principle of this type polarizing beam splitters was discussed in detail. It was found that the number of layers of a thin-film assembly, match of refractive index, and shift of reference wavelength are important parameters in designing ...

Polarizing beam splitter in terahertz regime
SPIE Proceedings, 2012Over the past ten years, electromagnetic terahertz (THz) frequencies region from 100 GHz to 10 THz (or wavelengths of 30μm-3mm) have received extensive attention and investigation. Terahertz wave detection enables direct calculations of both the imaginary and the real parts of the refractive index without using the Kramers-Kronig relations. There are

Orthogonal circular polarization axicon beam splitter
Microwave and Optical Technology Letters, 2000The design of an orthogonal circular polarization axicon beam splitter (OCPABS) that generates orthogonal circular polarization states (OCPS) is presented. The OCPABS consists of an absorbing V-shaped substrate coated with a transparent single-layer thin film.

A transmission polarizing beam splitter grating
Journal of Optics A: Pure and Applied Optics, 1999We present the design, fabrication, and test of a polarizing beam splitter grating for operation at 633 nm under a angle of incidence. This component is compact and its fabrication is reproducible enough to be integrated in optical reconfigurable interconnect systems.

Practical layer designs for polarizing beam-splitter cubes
Applied Optics, 2004Liquid-crystal-on-silicon- (LCoS-) based digital projection systems require high-performance polarizing beam splitters. The classical beam-splitter cube with an immersed interference coating can fulfill these requirements. Practical layer designs can be generated by computer optimization using the classic MacNeille polarizer layer design as the ...

Photonic Crystal Polarizing and Non-Polarizing Beam Splitters
Chinese Physics Letters, 2008A polarizing beam splitter (PBS) and a non-polarizing beam splitter (NPBS) based on a photonic crystal (PC) directional coupler are demonstrated. The photonic crystal directional coupler consists of a hexagonal lattice of dielectric pillars in air and has a complete photonic band gap.

Polished-type couplers acting as polarizing beam splitters
Optics Letters, 1986The theory is given for polarizing beam splitters made from polished-type directional couplers using anisotropic core material. A comparison is made between these beam splitters and those of the fused, biconical type.

Practical Thin-film Polarizing Beam-splitters
Optica Acta: International Journal of Optics, 1977Polarizing beam-splitters of the cemented cube form are considered and the designs of a number of multilayer thin-film coatings of ZnS and cryolite giving polarizing efficiencies at the design wavelength of greater than 99·8 per cent are discussed. The refractive index of the cube is chosen to match that of the optical cement, so that wedge fringes due
