Abstract

Indium-tin-oxide nanowhiskers were employed as transparent electrodes in a liquid-crystal terahertz phase shifter. Transmittance of the device was as high as ∼75%. Phase shift exceeding π/2 at 1.0 THz is achieved in a ∼500 μm-thick cell. The driving voltage required for the device operating as a quarter-wave plate was as low as 17.68 V (rms), an improvement of nearly an order of magnitude over previous work.

摘要

氧化铟锡纳米晶须被用作液晶太赫兹移相器中的透明电极。该器件的透过率高达约75%。在一个厚度约为500μm的单元中，在1.0太赫兹时实现了超过π/2的相移。该器件作为四分之一波片工作所需的驱动电压低至17.68伏（均方根值），比之前的工作提高了近一个数量级。
