160-GHz pulse generator using a 40-GHz phase modulator and PM fiber

Multi-channel 160-GHz pulse generator using a 40-GHz phase modulator and two stages of PM fiber

“…Recently, we have demonstrated a single-channel 160-GHz carrier-suppressed-return-to-zero (CS-RZ) optical pulse train generation by employing a phase modulator that is driven by a clock at only one-fourth of the bit rate [8]. In this paper, we extend it for WDM applications and demonstrate ITU-grid multi-channel 160-GHz optical pulse train generation by using a single set of phase modulator and two stages of polarization-maintaining (PM) fiber.…”
