Polarization Independent Optical Coherence Tomography [PDF]

open access: yesIEEE Photonics Journal, 2022
Optical coherence tomography (OCT) is a well established imaging modality for high-resolution three-dimensional imaging in clinical settings. While imaging, care must be taken to minimize the imaging artifacts related to the polarization differences ...

Polarization Independent Unidirectional Scattering With Turnstile Nanoantennas [PDF]

open access: yesIEEE Photonics Journal, 2020
We study the scattering behavior of a dielectric cross-dipole nanoantenna in the near-infrared spectral range when it is excited by a circular polarized plane wave.

A Polarization-Independent Fiber-Optic SPR Sensor [PDF]

open access: yesSensors, 2018
Fiber-optic surface plasmon resonance (SPR) sensors possess the advantages of small size, flexible, allowing for a smaller sample volume, easy to be integrated, and high sensitivity. They have been intensively developed in recent decades.

Polarization-Independent All-Optical Regenerator for DPSK Data [PDF]

open access: yesPhotonics, 2014
We demonstrate polarization-independent simultaneous all-optical phase-preserving amplitude regeneration and wavelength conversion of NRZ differential phase shift keying (DPSK) data by four-wave mixing (FWM) in a semiconductor optical amplifier (SOA ...

Polarization-Independent Nematic Liquid Crystal Phase Modulators. [PDF]

open access: yesACS Photonics
In this paper, we investigate the potential of achieving polarization independent phase modulation using supertwisted nematic (STN) liquid crystal (LC) devices. Here, we describe the use of a burst driving voltage applied to a 180° STN LC device to obtain a twist symmetric H (T-Hs) state, which enables simultaneous modulation of light for all ...
