Polarization modulation in optoelectronic generation and detection of terahertz beams

Compared with the conventional laser amplitude modulation with a lock-in amplifier, the optical polarization modulation in optoelectroni c generation and detection of a free-spac e terahert z ~THz! radiation provides up to twofold increase of the dynami c range. The total laser power for the optoelectroni c generation of THz beams can be fully utilized… CONTINUE READING
