使用市售材料 (E7) 制造的液晶器件已通过高达 4.5 THz 的太赫兹时域光谱进行了表征。这些 LCD 用于调制 3.4-THz 量子级联激光器的功率输出，根据液晶层厚度和所施加的偏置电压，将通过设备的太赫兹功率衰减高达 40%。
Liquid crystal devices manufactured with a commercially available material (E7) have been characterized with THz time-domain spectroscopy up to 4.5 THz. These LCDs were used to modulate the power output of a 3.4-THz quantum-cascade laser, attenuating the THz power through the device by up to 40% dependent both on the liquid crystal layer thickness and bias voltage applied.
