Polarization-insensitive dual-band response governed by quasi bound states in the continuum for high-performance refractive index sensing

Results in Physics, 2022
The introduction of distortions into the metasurfaces with in-plane symmetry offers a possibility to achieve resonances with high quality (Q) factors, but such distortions make the metasurfaces sensitive to the polarization state of the incident light ...

Metasurface-based broadband polarization-insensitive polarization rotator.

Optics Express, 2022
The polarizations of electromagnetic (EM) waves are very important for transceivers. We propose a broadband polarization-insensitive polarization rotator (PIPR), which can realize 90° polarization rotation for incident waves with an arbitrary azimuth ...

Polarization-Insensitive Remote Access Unit for Radio-Over-Fiber Mobile Fronthaul System by Reusing Polarization Orthogonal Light Waves

IEEE Photonics Journal, 2016
To reduce the complexity and cost of remote access units (RAUs), colorless transport architecture is preferred in a wavelength-division multiplexing (WDM) system. The wavelength-reuse technique is commonly adopted to realize colorless RAUs.

Polarization-Independent and Angle-Insensitive Metamaterial Absorber Using 90-Degree-Rotated Split-Ring Resonators

International Journal of Antennas and Propagation, 2015
We present the design, simulation, and measurement of a polarization-independent and angle-insensitive metamaterial absorber (MA) in X-band. Since the unit cell of the MA consists of four subwavelength split-ring resonators with 4-fold symmetric rotation,

Polarization insensitive metamaterial absorber based on E-shaped all-dielectric structure [PDF]

Journal of Advanced Dielectrics, 2015
In this paper, we designed a metamaterial absorber performed in microwave frequency band. This absorber is composed of E-shaped dielectrics which are arranged along different directions. The E-shaped all-dielectric structure is made of microwave ceramics

Actively stabilized wavelength-insensitive carrier elimination from an electro-optically modulated laser beam

, 2012
We demonstrate a simple and robust technique for removal of the carrier wave from a phase-modulated laser beam, using a noninterferometric method that is insensitive to the modulation frequency and instead exploits the polarization dependence of electro ...
