Noise Analysis and Optimization of Terahertz Photoconductive Emitters

  title={Noise Analysis and Optimization of Terahertz Photoconductive Emitters},
  author={Lei Hou and Wei Shi and Suguo Chen},
  journal={IEEE Journal of Selected Topics in Quantum Electronics},
The electromagnetic noise generated by terahertz photoconductive emitters was investigated, and the intensity of noise spectrum was analyzed by statistical method. The relationship between the noise of the emitter and the resistivity as well as carrier lifetime of the antenna material was obtained. And the effect of carrier lifetime and mobility of antennas on the THz generation efficiency was investigated. Based on those results, GaAs:O material was fabricated by an ion implantation technique… CONTINUE READING
