6. Optical pulse excitation sources
6.1 Photo-commutation
Photo-switching is the most efficient pulse method when low-power femtosecond lasers are available. It was the driving force behind the research and development of THz technology in the late 1980s.
SCROLL TO TOP6.1.1 Photocommutator antenna principle
A metal line is deposited on an undoped (semi-intrinsic) semiconductor substrate, which is insulating in the absence of illumination (figure 12 ). This...
