The Effects of Intracavity Phase Modulation and Extracavity Optical Filtering on Amplitude Noise of Mode-Locked Pulse Trains
(Institute of Electrical and Electronics Engineers Inc., 2018-09) Özharar, Sarper; Ozdur, Ibrahim T.
An actively mode-locked, fiber-coupled semiconductor ring laser that employs both a phase modulator and an amplitude modulator was built. The laser was mode-locked by loss modulation at 10 GHz and the intracavity phase modulator was driven at the cavity fundamental frequency of 1.63 MHz. The effects of the intracavity phase modulation on the stability of the optical spectrum, the timing jitter, and the amplitude noise of the pulse train was analyzed. It was found that using this method, the amplitude fluctuation can be reduced by 40%, and the stability of the optical spectrum can be improved while keeping the phase noise of the system unchanged. © 2019 Elsevier B.V., All rights reserved.
RF Phase Noise Filtering Effects of Mode-Locked Lasers
(Optica Publishing Group (formerly OSA), 2017) Ozdur, Ibrahim T.; Özharar, Sarper
In this manuscript, we have presented the results for RF phase noise filtering effects of mode-locked lasers. Our results show that, the phase noise of a 10GHz RF tone can be filtered by 10 dB. © 2023 Elsevier B.V., All rights reserved.
