We report the triple-functionality at 10-Gb/s of an integrated R-EAM-SOA, including modulation, detection and noise-mitigated 2R all-optical signal regeneration. The obtained results demonstrate its high potential for a multi-operation device in colorless WDM access networks.
Transmission of a 170 Gbit/s signal at 1550 nm was demonstrated in an integrated erbium-doped waveguide amplifier. Open eye diagrams and no power penalty were observed with the amplifier in the transmission system.
The spectral dependence of the gain and noise characteristics of a gas source molecular beam epitaxy (GSMBE)-grown BH-GaInAsP near-travelling-wave semiconductor laser amplifier are presented, from which an indication of nonresonant internal losses is given. An intrinsic noise figure of 6 dB at an internal gain of 28 dB is obtained.<<ETX>>
