Paper Abstract

With a unique 3D geometry, a broadband polarizer and single-polarization resonator are demonstrated by wrapping a microfiber on a specialized rod with a hybrid polymer-metal-dielectric nanostructure, respectively. The polarizer has an extinction ratio of more than 20 dB over the spectra range of 450 nm. The resonator has a Q-factor of ~ 80,000 with excellent suppressing of polarization noise. By functionalizing the rod surface with nanoscale silver film and tuning the coil geometry, performances can be improved by optimizing those parameters. Such kind of miniature singlepolarization microfiber and resonator are impossible to be realized by conventional fabrication process, and has the potential in gyro and current sensors.
