Polarization Degrees of Freedom
2008 IEEE International Symposium on Information Theory, 2008This paper unifies the different conclusions on the polarization degrees of freedom in multiple-antenna channels. It shows that the multiplicative gain in the degrees of freedom from polarization depends on the array geometry and the scattering condition.

Optical Coherence Engineering in the Polarization and Spatial Degrees of Freedom
Journal of Modern Optics, 2019We report a method to synthesize the complete range of arbitrary combinations of coherences independently in both the polarization and spatial degrees of freedom (DoFs) by utilizing energy conservi...

Full‐Color Holographic Display and Encryption with Full‐Polarization Degree of Freedom
Advanced Materials, 2021AbstractMetasurfaces provide a compact and powerful platform for manipulating the fundamental properties of light, and have shown unprecedented capabilities in both optical holographic display and information encryption. For increasing information display/storage capacity, metasurfaces with more polarization manipulation channel and full‐color ...

Polarization Toffoli gate assisted by multiple degrees of freedom
Optics Letters, 2018A Toffoli gate plays a critical role in many quantum algorithms due to its function as a building block, which is a fundamental element for feasible large-scale quantum computation. With the help of polarization, spatial, and temporal degrees of freedom (DOFs), a construction scheme of a nearly deterministic polarization Toffoli gate is proposed, where

Polarization-Based Zero Forcing Suppression With Multiple Degrees of Freedom
2011 - MILCOM 2011 Military Communications Conference, 2011Polarization-based suppression with zero forcing (ZF) is limited by similarities in the polarization-frequency response of the desired and interference signals. At subcarriers where the responses are similar, suppression of the interference also leads to suppression of the desired signal, and achievable cancellation ratios are correspondingly limited ...

On the degrees of freedom in linear array systems with tri-polarized antennas
IEEE Transactions on Wireless Communications, 2008In this paper, we provide a theoretical, simulation and experimental characterization of the performance of linear arrays of tri-polarized dipole antennas in multiple input multiple output (MIMO) systems in terms of degrees of freedom and channel capacity.

Polarization and Modal Degrees of Freedom for Tight Confinement of Light
Frontiers in Optics 2010/Laser Science XXVI, 2010We describe our work on tight confinement of light using plasmonic structures. Polarization and modal degrees of freedom are shown to have a crucial effect on the nanoscale focusing properties of the optical field.

Generation and manipulation of polarization-twisting dual pulses with a high degree of freedom
Optics Letters, 2020A polarization-twisting dual-pulse (PTDP) system is demonstrated using a modified Michelson interferometer (MI), in which a pellicle beam splitter is inserted into each arm. By tuning the positions of the end mirrors and pellicle beam splitters in the MI, the polarization-twisting frequency, the helicity, and the interval between two pulses can be ...
