We demonstrate multi-channel NRZ signal regeneration with NRZ-RZ-NRZ regenerative format conversion, using a phase-modulator and two fiber MZIs. Q improvements for eight 20Gb/s channels and BER for two representative channels demonstrate regeneration is achieved simultaneously.
We demonstrate multi-channel RZ signal regeneration based on a phase-modulator and an AWG. BER improvements for 8 10 Gb/s channels after 450 km transmission demonstrate that regeneration with timing jitter reduction and dispersion compensation can be achieved.
We propose and demonstrate a novel NRZ-DPSK-WDM system which can simultaneously demultiplex and demodulate multiple-wavelengths using single commercial AWG for rates between 10 and 40 Gb/s. BER results after transmission show the practicality of the system.
Ultra-fast self-routing of DPSK signals is demonstrated using a single processor for multiple spectral codes based on four-wave-mixing and selective filtering. A family of 10 codes with maximum bin separation for 10 and 20 Gb/s rates is demonstrated.
A fibre-radio access network architecture for simultaneous wireline and wireless transmissions of data over cable service interface specification (DOCSIS) signals is presented. An all-optical harmonic up-conversion technique using a dual-drive Mach-Zehnder modulator (DD-MZM) is employed at the central station while an InGaAsP/InGaAsP multiple quantum well (MQW) asymmetric Fabry-Perot modulator/detector...
