Counter-phase modulation of WDM 24×100 Gb/s DP-QPSK channels in a polarization-insensitive fiber-loop is demonstrated for low noise degenerate four-wave mixing with a CW pump. The OSNR is boosted by ≈9 dB enabling an average ≈4 dB Q2-factor improvement.
We demonstrate for the first time simultaneous chromatic dispersion and amplified-spontaneous-emission noise monitoring of phase-modulated 40 Gb/s NRZ-DPSK and 640 Gb/s RZ-DPSK optical signals, using a THz bandwidth photonic-chip-based radio-frequency spectrum analyzer. High measurement dynamic range was also achieved.
We theoretically and experimentally investigate the performance of two self-heterodyne detected radio-over-fiber (RoF) links employing phase modulation (PM) and quadrature biased intensity modulation (IM), in terms of bit-error rate (BER) and optical signal-to-noise ratio (OSNR). In both links, self-heterodyne receivers perform down-conversion of the RF subcarrier signal. A theoretical model including...
We analyzed 10 GHz NRZ-DPSK signals' PM-AM conversion process and demonstrated chromatic dispersion (CD) and OSNR monitoring simultaneously based on measuring 010 GHz RF spectrum power of the PRBS signals. The monitoring range of CD and OSNR are up to 4320 ps/nm and 10-30 dB respectively.
