Circular birefringence
Webcircular birefringence [ ′sər·kyə·lər ‚bī·rə′frin·jəns] (optics) The phenomenon in which an optically active substance transmits right circularly polarized light with a different velocity from left circularly polarized light. McGraw-Hill Dictionary of Scientific & Technical Terms, 6E, Copyright © 2003 by The McGraw-Hill Companies, Inc. WebCircular birefringence and optical rotation Chiral molecules exhibit circular birefringence, which means that a solution of a chiral substance presents an anisotropic medium through which left circularly polarised (L-CPL) and right circularly polarised (R-CPL) propagate at different speeds.

WebCircular birefringence. In 3d-chiral media, circularly polarized electromagnetic waves of opposite handedness can propagate with different speed. This phenomenon is known as circular birefringence and described by different real parts of refractive indices for left- and right-handed circularly polarized waves. WebOct 26, 2024 · In a broad number of optical fiber systems, a uniform twist rate is applied along the fiber, such as fiber Bragg gratings [1–3], interferometric schemes [4, 5], fiber optic sensors based on induced circular birefringence [6–8], optical signal processing devices [], mode-locked fiber lasers (ML-FL) [10–14] and so on.In most of these physical contexts, …
WebCircular Birefringence One can also describe optical activity as a difference of the velocity of light ( phase velocity) between two opposite rotation directions of circularly polarized light. That property of the medium is called circular birefringence. WebHigh-speed circular birefringence modulation is demonstrated with modest shearing speeds, indicating the potential for these concepts to dynamically control polarization states with fast temporal responses. We anticipate that fractured geometric phase metasurface systems will serve as a nanophotonic platform that leverages systems-level ...

WebOct 26, 2024 · In this model, the polarization evolutions of the continuous wave and the pulse profile are studied by the changes in ellipticity and ellipse rotation, which are driven by the inherent linear birefringence of the optical fiber, the induced nonlinear birefringence due to the centrosymmetric response of the fiber and the induced circular …
Circular birefringence and circular dichroism are the manifestations of optical activity. Optical activity occurs only in chiral materials, those lacking microscopic mirror symmetry. Unlike other sources of birefringence which alter a beam's state of polarization, optical activity can be observed in fluids .
