All-optical wavelength conversion and broadcasting to eight separate channels by a single semiconductor optical amplifier delay interferometer

Abstract

We have demonstrated an all-optical broadcast experiment in which a 10 Gbit/s RZ data signal is simultaneously converted into up to 8 different wavelengths. A single SOA with delay interferometer was used. Bit error rate measurements showed a power penalty of less than 1.5 dB for configurations with up to 8 wavelengths.
