Circular polarization detector based on polarization holography

Optics Letters, 2022
We propose and experimentally demonstrate the generation of a circular polarization detector based on planar polarization holography. The detector is designed by constructing the interference field according to the null reconstruction effect. We create multiplexed holograms, which feature the combination of two sets of hologram patterns and operate ...

Fiber circular polarizer

Applied Optics, 1983
A fiber circular polarizer, composed of a metal-coated fiber polarizer and a lambda/4 platelet fabricated on a birefringent fiber, has been demonstrated. The lambda/4 platelet was made by cutting a birefringent fiber to an appropriate length. The device structure was designed by stress analysis simulation using a finite element method to set the angle ...

Polarization-Sense Reconfigurable Circular Polarized Antenna

2020 International Symposium on Antennas and Propagation (ISAP), 2021
A single fed circular polarized microstrip patch antenna excited through near field coupling is proposed. L-shape near-field feed line is used to feed the microstrip patch antenna as it is useful to control the direction of the current, and change the polarization sense of the circularly polarized wave.

Superachromatic circular polarizer

Measurement Science and Technology, 2000
We present a design for a superachromatic circular polarizer that can be constructed with conventional, two-element, achromatic half-wave and quarter-wave retarders and used over the whole range of visible wavelengths.

Circular-polarization modulator

Nature Photonics, 2017
Switching the handedness of circularly polarized light requires separately controlling the phases of orthogonal components while maintaining their magnitudes, ideally with gigahertz operation rates. Ultrafast switching has now been realized via all-optical control of birefringent metamaterials.

Circular Polarized LCD

Molecular Crystals and Liquid Crystals Science and Technology. Section A. Molecular Crystals and Liquid Crystals, 1998
Abstract Novel LCD, which transmits circularly polarized light, is reported. The circular polarized light enables us to see the LCD screen through polarized sunglasses. It is developed for outdoor application, such as mobile computing, car navigator, and so on. The circular light is achieved by placing additional quarter wave film upon the screen.
