Abstract

Phase shift exceeding π2 at 1THz is demonstrated by using electrically controlled birefringence in a homeotropically aligned nematic liquid crystal (E7) cell, 570μm in thickness. The driving voltage required for a phase shift of 90° is 125V (rms). We demonstrate that the phase shifter works as an electrically switchable quarter-wave plate at 1THz. The device can also be used as an electrically tuned phase compensator around the quarter-wave point near 1THz.
