Webbon the Poincaré sphere act through the spin-1/2 representation. In Sec. 3 we review the effect of some optical filters and its geometrical representation on the Poincaré sphere. We show that the effect of a phase shifter corresponds to a rotation of the Poincaré sphere, while that of an 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 …

A … 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.
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.
