THE FREQUENCY TUNABLE TERAHERTZ CONTINUOUS WAVE GENERATION APPARATUS

摘要

PURPOSE: A frequency tunable terahertz continuous wave generating apparatus is provided to generate a terahertz continuous wave using a DSB-SC method. CONSTITUTION: An optical signal generator(200) modulates a double side band optical signal by a DSB-SC(Double Side Band-Suppressed Carrier) mode n times. The optical signal generator generates several double side band optical signals. The optical signal generator selectively eliminates an unnecessary optical signal from the several double side band optical signals. The optical signal generator generates two optical signals of different wavelengths. An optical signal converter(300) converts two optical signals generated in the optical signal generator into terahertz continuous waves.
