Hybrid access network integrated with multi-level wireless vector signal and wireline OOK signal without optical filter is proposed for the first time. 312.5-MSymbol/sec RF 8-PSK signal and 1.25-Gb/sec BB signal are experimentally demonstrated.
A coherent receiver with feedback was developed to linearly demodulate the phase of an analog signal. The receiver demonstrates a spur-free dynamic range of 125 dBmiddotPHz2/3 at a signal frequency of 300 MHz.
This investigation experimentally demonstrates the performance improvement in fiber- radio links by using a semiconductor laser. This technique improves receiver sensitivity over 4.5 dB by increasing the optical modulation depth.
We demonstrate large-scale, long-term stable, and femtosecond-precision timing distribution and synchronization systems based on optical pulse trains generated from ultralow-noise mode-locked lasers.
This work investigates a novel phase noise averagers to suppress IFWM-induced phase noise of RZ-DPSK signals. Both analytical and simulation results confirm that the IFWM-induced phase noise will be converged, even after an ultra-long transmission.
A novel bi-directional DPSK transmission system with 50-GHz channel spacing is experimentally demonstrated using a four-port interleaver to enable uni-directional amplification. After 230-km SSMF, RZ-DPSK transmission improved power penalty by 2-dB than NRZ-DPSK at 10-Gb/s.
We analytically computed the optical spectra and numerically evaluated the ripple impacts on the performance of an optical DQPSK signal generated by only one MZM. We confirmed the necessity of a pulse carver to this kind of signal. The tolerances to the timing mismatch between the data and the pulse carver were analyzed among different duty-cycles. The conventional DQPSK signal generated by two parallel...
We proposed and experimentally demonstrated a bidirectional transmission system by using a novel four-port interleaver to enable unidirectional amplification. After 210-km transmission, less than 0.2-dB sensitivity variations were observed between bidirectional and unidirectional transmissions
