Wearable Conformal Metasurfaces for Polarization Division Multiplexing

Advanced Optical Materials, 2020
AbstractIn practice, there is a strong requirement for modulating the performance of existing bulk devices without changing their physical geometry. In this study, by attaching a flexible metasurface on a cylindrical lens, a wearable conformal metasurface for terahertz polarization division multiplexing is demonstrated, which could be used in wireless ...

Gigabit polarization division multiplexing in visible light communication

Optics Letters, 2014
In this Letter, polarization division multiplexing is proposed and experimentally demonstrated for the first time that we know of, in visible light communication systems based on incoherent light emitting diodes and two orthogonal groups of linear polarizers.

On-chip multiplexing conversion between wavelength division multiplexing–polarization division multiplexing and wavelength division multiplexing–mode division multiplexing

Optics Letters, 2014
A compact silicon-on-insulator device used for conversions between polarization division multiplexing (PDM) and mode division multiplexing (MDM) signals is proposed and experimentally demonstrated by utilizing a structure combining the improved two-dimensional grating coupler and two-mode multiplexer.

Visible light communications: increasing data rates with polarization division multiplexing

Optics Letters, 2020
In this Letter, we propose a new configuration for visible light communication systems, which results in doubling of the data rate due to the use of polarization division multiplexing. As light-emitting diodes are unpolarized incoherent light sources, we isolate both the perpendicular s and parallel p modes for

Polarization-Division-Multiplexed Nonlinear Frequency Division Multiplexing

Conference on Lasers and Electro-Optics, 2018
We experimentally demonstrate dual-polarization nonlinear frequency division multiplexing using the continuous spectrum in 1680 km of normal dispersion fiber at a burst rate of 128Gbit/s. The DGD penalties are shown to be negligible.

Polarization division multiplexing with subpicosecond solitons

Conference Proceedings. LEOS '97. 10th Annual Meeting IEEE Lasers and Electro-Optics Society 1997 Annual Meeting, 2002
After introducing perturbation terms to the Manakov equation to account for higher-order dispersion and for the Raman effect, we analyze polarization division multiplexing with subpicosecond solitons. Dispersion-shifted single-mode fibers operating at 1.55 /spl mu/m are considered.

Polarization division multiplexed optical eigenvalue modulation

2015 International Conference on Photonics in Switching (PS), 2015
We propose a polarization division multiplexed optical eigenvalue modulation scheme based on the invariant property of eigenvalue associated to Manakov equation. We numerically demonstrate the feasibility of the proposed scheme.

Silicon-Based Hybrid (de)Multiplexer for Wavelength-/Polarization-Division-Multiplexing

Journal of Lightwave Technology, 2018
A novel hybrid multiplexer for wavelength-division- multiplexing (WDM) and polarization-division-multiplexing (PDM) is proposed and realized by integrating a polarization-splitter-rotator (PSR) and an optical-filter array based on novel microring resonators (MRRs).

Manipulating Polarization-division Multiplexed Terahertz Signals with Four-wire Waveguides

Proceedings of the 2022 Conference on Lasers and Electro-Optics Pacific Rim, 2022
We demonstrate a new metal-wire waveguide topology, namely a four-wire waveguide, which simultaneously acts as a broadband terahertz polarization-division multiplexer and a novel platform to realize the independent manipulation of polarization-division multiplexed terahertz signals.
