Abstract

Tunable and reconfigurable devices for efficiently manipulating THz waves in advanced sensing, imaging and communication are challenging to realize. An alternative promising approach for developing the above THz devices based on spatially-resolved optical modulation (SROM) will be introduced followed by prototype demonstrations. Enhanced SROM using mesa-array structures for more advanced tunable/reconfigurable THz devices will be presented. High-performance optically-controlled THz switches enabling next generation adaptive integrated THz circuits/systems will then be discussed. Finally, in addition to magnitude modulation, a unique approach for achieving high-performance THz phase shifting will be proposed, making the SROM a more complete, systematic and versatile/powerful technology for manipulating THz waves.
