Tufts engineers develop modulator to help fill the terahertz gap

165
Engineers at Tufts University are looking to fill the terahertz gap—the band of frequencies between microwaves and infrared for which practical applications remain elusive. The engineers put the have invented a chip-sized modulator that operates at terahertz frequencies at room temperature with low drive voltages (less than 2 V) and zero DC power. Measurements show the modulation cutoff frequency of...
