Abstract: Disclosed is an optical pulse adjusting device including a pulse shaper that receives an input signal generated based on an optical frequency comb (OFC) signal and outputs a spectrum adjustment signal by adjusting an optical spectrum shape of the input signal, an optical amplifier that outputs an optical amplification signal by amplifying the spectrum adjustment signal, an optical spectrum analyzer (OSA) that outputs an information signal by comparing an optical spectrum shape of the optical amplification signal with a target optical spectrum shape, and a control circuit that outputs a comparison signal based on the information signal. The pulse shaper further receives the comparison signal and adjusts the optical spectrum shape of the input signal based on information about a difference between the optical spectrum shape of the optical amplification signal and the target optical spectrum shape, which is included in the comparison signal.
