Low-Profile FSS-Based Polarization-Insensitive Rasorber With Switchable Transmission Band

IEEE Antennas and Wireless Propagation Letters, 2021
In this letter, a new polarization-insensitive, low profile frequency-selective rasorber (FSR) is presented with a switchable transmission band. This FSR consists of a lossy layer, a bandpass layer, and a switchable layer where p-i-n diodes are mounted ...

Polarization-insensitive photonic microwave downconversion

Optics Letters, 2013
A polarization-insensitive photonic microwave downconverter is proposed and demonstrated, which is comprised of a polarization beam splitter, two Mach-Zehnder modulators (MZMs), and a balanced photodetector. By biasing the MZMs at the quadrature bias points with opposing modulation slopes, the performance of the proposed photonic microwave ...

Polarization insensitive hydrophone

The Journal of the Acoustical Society of America, 1996
A hydrophone is formed of first and second optical fibers coupled together to form a fiber optic interferometric sensor for sensing an acoustic signal. The optical fibers are wrapped around a pair of concentric, thin-walled hollow cylinders. The fiber wrapped around the inner cylinder is the reference leg of the interferometer and the fiber wrapped ...

Analysis of a semiconductor optical amplifier with polarization-insensitive gain and polarization-insensitive phase modulation

Semiconductor Science and Technology, 2006
The polarization dependence of phase modulation in a semiconductor optical amplifier (SOA) has negative impacts on some pump/probe applications of SOAs. We propose the necessity of fabricating SOA with polarization-insensitive gain and polarization-insensitive phase modulation and study the possibility.

Polarization insensitive laser stabilizer

SPIE Proceedings, 1994
Polarization insensitive laser stabilizer which can be used for both polarized and unpolarized beams is presented. The system utilizes a polarization independent variable attenuator which is composed of two identical polarization beamsplitting prisms and an improved Pockels cell to control the incoming laser beam intensity.

Polarization-Independent Broadband Optical Regime Metamaterial Absorber for Solar Harvesting: A Numerical Approach

, 2021
In this article, a broadband metamaterial (MTM) absorber is proposed that exhibits near-unity absorption in the terahertz regime. The proposed metamaterial absorber was initiated on a quartz (fused) substrate, whereas the resonator and backplane are ...

Polarization-Insensitive Isolators and Circulators on InP Photonics

2023 Optical Fiber Communications Conference and Exhibition (OFC), 2023
On-chip isolators and circulators are regarded as the last piece of puzzle for photonic integrated circuits. In this paper recent successful demonstration of a polarization insensitive design, compatible with the InP laser process on a thin membrane, is presented.

Polarization Insensitive and Transparent Frequency Selective Surface for Dual Band GSM Shielding

IEEE Transactions on Antennas and Propagation, 2020
This article proposes a single-layer, dual-band, optically transparent frequency-selective surface (FSS) for GSM shielding. The design evolves from a fractal cross dipole to achieve dual-band response, polarization insensitivity, and wide angle of ...

Broadband Polarization-Insensitive Tunable Absorber Using Active Frequency Selective Surface

IEEE Antennas and Wireless Propagation Letters, 2020
In this letter, a broadband polarization-independent tunable absorber is proposed based on active frequency selective surface (AFSS). The AFSS consists of periodic patterns of four-patch array with four p-i-n diodes loaded among them, and a simple bias ...

On-chip polarization-insensitive Fourier transform spectrometer

Optics Letters, 2020
Chip-scale monolithic Fourier transform spectrometers (FTSs) offer great potential for inexpensive, high-resolution, and robust spectroscopic applications in a wide variety of scenarios. Having attracted considerable attention, spatial heterodyne FTSs (SH-FTSs) are featured with a simple and stable configuration composed of an array of Mach–Zehnder ...
