Abstract
A sample realizable method for terahertz wave modulation is demonstrated experimentally by using optical controllable ultra‐high resistivity silicon wafer. With modulated 100 mw of 808 nm CW light, a maximum of 21 dB terahertz attenuation was achieved with 0.2 kb/s of modulation speed. The experimental results show good agreement with the Drude‐Lorentz model. Further work is underway to improve the modulation speed above Mb/s. © 2009 Wiley Periodicals, Inc.
