Integrated all-optical 2-bit decoder based on semiconductor optical amplifiers

In this paper, the architecture of an SOA-based N-bit decoder, with minimum number of SOAs using Cross-Gain Modulation (XGM), is described. A 2-bit decoder is integrated under Multi-Project Wafer (MPW) photonic foundries in indium phosphide (InP) technology. Its output signals are analysed off chip and its performance is evaluated at 10 Gbps with RZ amplitude-modulated signals.
