Abstract

We propose a harmonically hybrid silicon mode-locked ring laser using intracavity reflectors (ICRs) to suppress supermode noise. The dynamic and noise properties of the structure are investigated using a delay differential equation model. The results of the dynamic show that a 20 GHz harmonic regime of the structure is significantly increased compared to a without intracavity–reflector structure. Additionally, the phase noise of the proposed structure (PS) is improved to about 8 dB. Furthermore, an analysis shows that timing jitter reduction has periodic behavior by changing the harmonic inter-spike interval time (${T_{{\rm ISI}}}$).
