Quantum dot SOA input power dynamic range improvement for differential-phase encoded signals
15 March 2010
Experimentally we find a 10 dB input power dynamic range advantage for amplification of phase encoded signals with quantum dot SOA as compared to low-confinement bulk SOA. An analysis of amplitude and phase effects shows that this improvement can be attributed to the lower alpha-factor found in QD SOA. (C) 2010 Optical Society of America
