title: Experimental investigation of chirp properties induced by signal amplification in quantum-dot semiconductor optical amplifiers.
abstract: We experimentally show the dynamic frequency chirp properties induced by signal amplification in a quantum-dot semiconductor optical amplifier (QD-SOA) for the first time. We also compare the red and blue chirp peak values and temporal chirp changes while changing the gain and injected signal powers of the QD-SOA with those of a common SOA.
