ABSTRACT:
Rapid, voltage controlled phase modulation of continuous wave THz radiation is demonstrated. By transmitting an infrared laser beam through a phase modulator, the phase of the THz radiation which is generated by the photomixing of two infrared beams can be directly modulated through a 2π phase shift. The 100 kHz modulation rate that is demonstrated is approximately three orders of magnitude faster than what can be achieved by mechanical scanning.
