Abstract :
THz waves have recently attracted considerable interest mainly because of their various applications. Efficient and compact CW sources are currently under development using either electronic or optical components. On the electronic side, an important innovation of last years has been to excite THz plasma oscillations in short gate length HEMT. On the optoelectronic side, high speed photodetectors and photodiodes are currently under development with aim of a most efficient coupling with already existing 1.55 μm semiconductor laser technology. Besides active device review, studies devoted to controllable THz photonic crystals and specific antennas for the THz domain will also be discussed.
