Abstract :
In this paper, a novel optical frequency 24-tupling scheme for THz signal generation is proposed and demonstrated. Based on two cascaded Dual-Parallel Mach-Zehnder Modulators (DPMZM) and three phase shifters, optical signal with only ±12th-order sidebands is achieved without optical filter. Theoretical analysis and simulation results show that the scheme can generate 0.12THz signal from a 5GHz radio frequency local oscillator (LO), and the harmonic distortion suppression ratio is more than 55 dB.
