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 ... WebMar 9, 2024 · In this work, an elimination method of the temperature-induced linear birefringence (TILB) in a stray current sensor is proposed using the cylindrical spiral fiber (CSF), which produces a large amount of circular birefringence to eliminate the TILB based on geometric rotation effect. First, the differential equations that indicate the …
WebThe measurement of linear birefringence of crystalline materials is described, together with some examples, showing how it is linked to crystal structures, particularly through the study of phase transitions. Circular birefringence (more commonly known as optical activity) has now also been related to structures of inorganic materials.
