… Abstract: 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. … 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 …
