摘要

以光混频器电路模型为基础，理论分析了碳纳米管（CNT）材料光混频器产生太赫兹功率的大小. 通过对光混频器电导、天线的阻抗和外加偏置电压的模拟结果表明：提高光混频器电导、天线阻抗和外加偏置电压都能够提高输出太赫兹波功率，在小信号输入条件下，输出功率理论上能够达到数十微瓦.

On the basis of mixer circuit model of light, the terahertz power generated by the carbon nanotubes (CNT) photomixer is analyzed. By simulating mixer conductance, impedance of the antenna, and light plus paranoid voltage, it is shown that the improved mixer conductance, antenna impedance and light plus paranoid voltage can improve the output power of terahertz waves. The output power can reach dozens of microwatt level in the small-signal limit.
