Abstract

Liquid crystal (LC) devices Submillimeter wave phase shifters Tunable circuits and devices Ultrafast optics
Tunable phase shift up to 360° at 1 THz is demonstrated using electrically controlled birefringence in a vertically aligned nematic liquid crystal (E7) cell, 1.83 mm in thickness. The driving voltage and corresponding field required for a phase shift of 360° at 1 THz are 100 V and 90.5 V/cm, respectively. © 2006 IEEE.
