Experimental polarization encoded quantum key distribution over optical fibres with real-time continuous birefringence compensation [PDF]

, 2009
In this paper we demonstrate an active polarization drift compensation scheme for optical fibres employed in a quantum key distribution experiment with polarization encoded qubits.

Recent advances in optical metasurfaces for polarization detection and engineered polarization profiles

Nanophotonics, 2020
Like amplitude, phase and frequency, polarization is one of the fundamental properties of light, which can be used to record, process and store information.

Evanescent wave induced polarization-insensitive self-organization of stratified single-negative materials

New Journal of Physics, 2021
Optical fields can induce optical forces between macroscopic objects, giving rise to different structures. Through rigorous calculation, we show that a collection of single negative slabs which possesses either negative permittivity or negative ...

Optical Nonlocality in Polar Dielectrics [PDF]

Physical Review X, 2020
Phonon polaritons localized in polar nanoresonators and superlattices are being actively investigated as promising platforms for midinfrared nanophotonics. Here we show that the nonlocal nature of the phonon response can strongly modify their nanoscale physics.

Optically-pumped dilute nitride spin-VCSEL [PDF]

, 2012
We report the first room temperature optical spin-injection of a dilute nitride 1300 nm vertical-cavity surface-emitting laser (VCSEL) under continuous-wave optical pumping.

Polarization Signatures of Relativistic Magnetohydrodynamic Shocks in the Blazar Emission Region - I. Force-free Helical Magnetic Fields [PDF]

, 2015
The optical radiation and polarization signatures in blazars are known to be highly variable during flaring activities. It is frequently argued that shocks are the main driver of the flaring events.

Analysis of Quantum-Dot Spin-VCSELs

IEEE Photonics Journal, 2012
The derivation of a set of rate equations (REs) to describe optically pumped quantum-dot (QD) spin-injected vertical-cavity surface-emitting lasers (VCSELs) is presented based on a modified version of the spin-flip model. The approach includes capture of

Odd Magneto-Optical Linear Dichroism in a Magnetophotonic Crystal

Photonics, 2023
The phenomena of magneto-optical polarization rotation and circular magnetic dichroism are well known in the Faraday configuration. We present another effect, an odd magneto-optical linear dichroism, arising in nanostructures with polarization-dependent ...

Highly efficient vectorial field manipulation using a transmitted tri-layer metasurface in the terahertz band

Opto-Electronic Advances, 2023
Polarization is a basic characteristic of electromagnetic waves that conveys much optical information owing to its many states. The polarization state is manipulated and controlled for optical information security, optical encryption, and optical ...
