Magnetic polarity switch
WebAn all-fiber interferometric switch based on Faraday rotation exhibited by magneto-optic materials in the presence of an external magnetic field is reported. The interferometer is Mach-Zehnder type and the related phase shift was obtained by the rotation of the state of polarization of a linearly polarized optical signal. The operation of the switch is … Web6 jul. 2024 · Additional resources.
