Abstract

This paper presents the results and analysis of semiconductor optical amplifiers (SOA) as applied in optical nodes for Photonic switching in OPS/OBS future networks. By the same token detailed characterization is provided to investigate physical constraints of optical power, gain and noise figure of SOAs. By using external cavity tunable laser and DFB laser sources, we verify that although the SOA gain is not sensitive to input source a significant influence on the noise figure (NF) of the amplifier is observed. Different analytical expressions for NF are used and consequently lead to different results, illustrating different aspects of devices.
