Low-Profile FSS-Based Polarization-Insensitive Rasorber With Switchable Transmission Band
IEEE Antennas and Wireless Propagation Letters, 2021In 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, 2013A 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, 1996A 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 ...

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, 1994Polarization 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 Insensitive and Transparent Frequency Selective Surface for Dual Band GSM Shielding
IEEE Transactions on Antennas and Propagation, 2020This 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 ...
