“…Another interesting frequency combs called microcomb soliton microcombs have diverse applications in the imaging, and in low noise microwave generations [18], [19]. The OFC can be generated by various techniques, including single or cascaded configurations of optical modulators [20]- [23], radio frequency shifting loops (RFS) [24], [25], mode-locked lasers [26]- [28], and self-oscillation loops [27], [29]- [36]. The RFS loops and mode-locked lasers also produce efficient results, but the system complexity is greatly increased.…”

“…Many researchers have proposed various topologies for generating OEO deployed for generating the OFC, this paragraph summarize most of the state-of-the-art techniques offered for designing OEO based OFCG. In [27], the authors proposed a OEO loop for OFC generation based on dual-mode microcavity laser. The OEO loop was designed by launching the into a SMF1 which is then detected by a photodetector (PD), following by two electrical amplifiers (EAs) to compensate the loss of the link.…”

A new optoelectronic oscillator (OEO) is implemented for a novel self-sustained flat-topped selfoscillating optical frequency comb generator (SO-OFCG), which can be deployed in terahertz optical transmission. The OFCG is designed from a cascaded configuration of an electro-absorption modulator and a polarization controller. In this work, the radio frequency source of a traditional-OFC scheme is replaced by the OEO. The frequency spacing of the generated spectrum is defined by the OEO~20GHz that contains 15-healthy frequency tones. The carriers are modulated using the 16-quadrature amplitude modulation technique and transmitted across an SSMF implemented in a loop to complete a fiber span of 80km-240km. Overall, 1.12Tbps transmission can be achieved with the help of the given setup. At the receiver side, a homodyne coherent receiver is designed using the proposed OFCG to receive the signal. The conventional local oscillator lasers are replaced by the SO-OFCG generated from the received central optical carrier. Through offline DSP, the received optical signals are remunerated from various signal distortions and nonlinear impairments by utilizing digital backpropagation, constant modulus algorithm, and blind phase search algorithm at the receiving end. The system is analyzed regarding the bit error rate, symbol error rate, Q-factor, and error vector magnitude.

“…Recently, microcavity lasers have stirred great interest in microwave photonics [33] and frequency comb generation [34][35][36] owing to small mode volume, high-quality factor, and planar integration capability. Dual-wavelength lasing with a certain degree of coherence was demonstrated with a square microcavity resonator [37].…”

A highly coherent optical frequency comb (OFC) based on spectral broadening of a phase-locked dual-wavelength microcavity laser is presented. By directly modulating the microcavity laser to generate multiple sidebands, the cross-injection locking of the dual modes is achieved and the beat-signal linewidth is improved from 13.5 MHz to less than 100 Hz. Subsequently, 21 flat comb teeth in a ±3 dB power variation are achieved by combining a phase modulator. Finally, an OFC with a bandwidth of 16 nm is successfully realized by narrowing the optical pulse and spectral broadening in a commercial nonlinear optical fiber. The repetition rate has a low phase noise of -102 dBc/Hz at 10 kHz offset, demonstrating the generated OFC has a high degree of coherence.
