40 nm broadband SOA-Raman hybrid amplifier

A hybrid SOA-Raman amplifier scheme with over 40 nm operational bandwidth has been demonstrated. This novel and simple configuration can significantly increase span length and optical signal-to-noise ratio. Q-factors are measured to optimize the operating condition for the two schemes. The performance is related to crosstalk in SOA and overall OSNR.
