We study the amplification of 40 Gb/s RZ signals (having 7 ps-long pulses) in a high gain (30 dB) semiconductor optical amplifier. We report an experimental comparison between straightforward amplification and amplification assisted by the use of both continuous wave (CW) and modulated holding beams.
Cross gain modulation between two different optical signals, inserted through separate ports to an active MMI, has been experimentally measured. The observed trend of modulation reduction by increase of modulated signal power matches previous simulation results. An associated XPM is expected and could be optimized to enable using the active MMI in all-optical switching.
Simultaneous inverted and non-inverted wavelength conversions (WCs) at 10 Gb/s with 2R regeneration are demonstrated using nonlinear polarization rotation in an SOA. A power penalty reduction of 1.2 dB for inverted WC and 0.8 dB for non-inverted WC is obtained at a BER of 10-9.
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.
Comparison on shortened falling-time, reduced chirp and improved on/off extinction ratio of 10 Gbit/s all-optical pulsed RZ generation in single-and multi-wavelength inverse-optical-comb injected semiconductor optical amplifiers with temporally reshaped gain-window is demonstrated.
