Polarization insensitive imaging through polarization gratings

Optics Express, 2009
Liquid crystal polarization gratings exhibit high diffraction efficiency (approximately 100%) in thin material layers comparable to the radiation wavelength. We demonstrate that they can be combined for polarization-insensitive imaging and optical switching applications.

Polarization-Independent Filter Based on 2-D Crossed Grating Under Oblique Incidence

IEEE Photonics Journal, 2018
The existing polarization-insensitive filters based on two dimensional (2-D) grating are mostly under normal incidence. However, in filtering optical devices, the normal incidence regime is usually avoided because it requires the use of beam separators ...

Incident-angle-insensitive and polarization independent polarization rotator

Optics Express, 2010
This paper proposes a method to design an incident-angle-insensitive polarization-independent polarization rotator. This polarization rotator is composed of layers of impedance-matched anisotropic metamaterial (IMAM) with each layer's optical axes gradually rotating an angle.

Highly sensitive and polarization-insensitive terahertz microfluidic biosensor based on gap plasmon model

Results in Physics, 2023
The gap plasmon resonance can generate a local enhanced electric field and make the electromagnetic field energy mostly confined in the microfluidic, thereby increasing the interaction between the detection sample and terahertz wave.
