terahertzwavephasemodulation is introduced. The analysis of the phasemodulator with inverse direction lightwave is successfully presented. … In this paper, we propose a novel phase-detection system using a pilot lightwave in the inverse direction of the phase modulator and theoretical analysis. We also show that the optical noises are successfully eliminated using a programmingbased feedback …
A photonics-based control system to stabilize the phases of the optical signal for terahertz wave phase modulation is introduced. The analysis of the phase modulator with inverse direction lightwave is successfully presented.
