Snapshot polarization-sensitive plug-in optical module for a Fourier-domain optical coherence tomography system [PDF]

, 2018
In this communication, we present a proof-of-concept polarization-sensitive Optical Coherence Tomography (PS-OCT) which can be used to characterize the retardance and the axis orientation of a linear birefringent sample.

Design and Optimization of a Broadband Polarization-Insensitive 90° Optical Hybrid in Double-Strip Silicon Nitride Waveguides

Photonics
Coherent optical communication serves as the backbone of long-haul, high-capacity optical networks, where polarization-insensitive 90° optical hybrids (OHs) are crucial for system simplification and robustness.

Polarization-insentivity for polymer-silica based multimode interference (MMI) cross couple [PDF]

, 2008
A polarization-insensitive cross coupler, which consists of hybrid polymer-silica-based multimode waveguide on Si substrate, is presented. At operation wavelength of 1.55 µm, the simulation was done for both TE and TM modes and it was found that there is

Polarization Insensitive Electro-optic Probe

Asia Pacific Optical Sensors Conference, 2016
A highly simple and polarization insensitive fiber-optic probe for electric field sensing is demonstrated. The polarization instability problem − often occurs due to the birefringence drift in lengthy optical fibers - is overcome for fiber-coupled optical sensors.

Design of a Polarization-Insensitive and Wide-Angle Triple-Band Metamaterial Absorber

Photonics
This paper proposes a tri-band wide-angle polarization-insensitive absorber operating in the C-band and Ku-band, based on the design concept of metal–dielectric–metal. The absorber achieves absorption efficiencies of 99.05%, 99.3%, and 97.9% at 4.23 GHz,

Programmable polarization-independent spectral phase compensation and pulse shaping by use of a single-layer liquid-crystal modulator

, 2020
What we believe to be the first use of a single-layer liquid-crystal modulator array for spectral phase pulse shaping that operates independently of input polarization is reported.

FSS inspired polarization insensitive chipless RFID tag

, 2017
A polarization insensitive, compact, fully-passive bit encoding structure exhibiting 1 : 1 resonator-to-bit correspondence is presented. Inspired by frequency selective surface (FSS) based microwave absorbers, the structure readily operates as a chipless

Polarization-insensitive silicon intensity modulator with a maximum speed of 224 Gb/s

Polarization-insensitive optical modulators allow an external laser to be remotely interconnected by single-mode optical fibers while avoiding polarization controllers, which would be convenient and cost-effective for co-packaged optics, 5G, and future ...

Design and characterization of a tunable polarization-independent resonant grating filter

We present the design, analysis and characterization of a polarization-independent tunable resonant grating filter. Polarization independence is achieved by setting the plane of incidence parallel to the grating grooves and optimizing the fill factor to ...
