Abstract: |
Active polarization switching devices are important to control the polarization state of light including terahertz (THz) waves that are technologically challenging to manipulate. Here, we propose and numerically demonstrate a hyperbolic metamaterial (HMM) based active Brewster polarization switch for the intensity and phase modulation of THz light. The proposed multilayered HMM consisting of alternating thin layers of high temperature superconductor such as YBCO (yttrium barium copper oxide) and dielectric material such as LAO (lanthanum aluminate). HMM shows elliptical dispersion above the superconducting phase transition temperature and type II hyperbolic dispersion in the superconducting state. By varying the temperature from dielectric to superconducting phase of the HMM, we demonstrate above 98% THz intensity modulation and 100% phase tunability (180 degrees) at the Brewster angle. The proposed HMM can work as an efficient reflective THz modulator by properly selecting the angle of incidence. |
