WebBy using chirped fiber Bragg gratings, mode-locked optical pulses can be made that appear as continuous wave signals that completely fill the mode-locked pulse period. In addition, optical amplifying systems can be configured that completely circumvent the conventional limitation imposed by short pulse gain saturation. WebJan 1, 2024 · The modulation signal is chirped with a period of 81.92us and frequency range from 8.4 GHz to 9.6 GHz. An optical coupler splits the output light into the probe light (90 %) and reference light (10 %) respectively. The main part of probe light is injected into the FUT through the optical circulator.
