摘要

采用三种不同设计的液晶太赫兹移相器，在1.0太赫兹处实现了超过2π的高透射率相移。采用氧化铟锡纳米晶须和石墨烯作为透明电极。2π波片所需的驱动电压低至5 Vrms。

Voltage-controlled Terahertz Phase Shifter with Functional Nanowhiskers and Graphene as Transparent Electrodes

Phase shift exceeding 2π at 1.0 THz with high transmittance was achieved in liquid-crystal THz phase shifters of three different designs. Indium-tin-oxide nanowhiskers and graphene were employed as transparent electrodes. The driving voltage required for a 2π wave plate is as low as 5 Vrms.
