The poincaré sphere
WebbThe angle χ is also significant in that the latitude (angle from the equator) of the polarization state as represented on the Poincaré sphere (see below) is equal to ±2χ. The special cases of linear and circular polarization correspond to an ellipticity ε of infinity and unity (or χ of zero and 45°) respectively. Webb14 mars 2016 · The Poincaré sphere is a Bloch sphere in which the basis states are two orthogonal states of polarization, whereas the HOP sphere is a Bloch sphere in which the basis states are more...

WebbHenri Poincaré was working on the foundations of topology—what would later be called combinatorial topology and then algebraic topology.He was particularly interested in what topological properties characterized a sphere.. Poincaré claimed in 1900 that homology, a tool he had devised based on prior work by Enrico Betti, was sufficient to tell if a 3 … Webb18 okt. 2024 · Here, we demonstrate an amplitude-phase-polarization joint modulation method to accurately control the variation of localized polarization during propagation, mapping arbitrary circular trajectory on the Poincaré sphere.
Webb6 dec. 2024 · Metasurfaces have recently enacted diverse electromagnetic manipulations in polarization optics. However, they only support one or a few polarization functions in a single design. Here, an arbitrary and dynamic Poincaré sphere polarization converter to implement full-polarization optics with a single time-varying metasurface is demonstrated. WebbThe Bloch sphere may be generalized to an n-level quantum system, but then the visualization is less useful. For historical reasons, in optics the Bloch sphere is also known as the Poincaré sphere and specifically represents different types of polarizations. Six common polarization types exist and are called Jones vectors.
WebbPoincaré's homology sphere is a closed 3- manifold with the same homology as the 3-sphere but with a fundamental group which is non-trivial. In his series of papers on Analysis situs (1892 - 1904) Poincaré introduced the fundamental group and studied Betti-numbers and torsion coefficients. He asked himself the question how strong these ...
