“…Environmental noise represents the main source of fluctuations. In comparison, using more complex architecture such as Pound-Drever-Hall stabilization, the frequency stability in terms of Allan deviation reaches a value of 10 -9 for 100 ms averaging time [27]. For some applications such as time and frequency metrology, a higher long-term stability is required.…”

This paper reports on the repetition frequency stability of InAs/InP quantum-dash based mode locked lasers emitting in the 1.55 µm telecom window and of a long-term frequency stabilization schemes. We discuss the main noise sources that affect the frequency stability. In free running operation, quantum-dash based mode locked lasers demonstrate an initial long-term stability of ~10 -7 . In order to improve it, we developed different approaches based on electrical feedback and optical feedback loops. The stabilization systems exploit the biasdependent frequency drift and the optical feedback sensitivity to keep repetition frequency in lock for an extensive period of time with a stability of 1.5x10 -9 .Index Terms-Mode locked semiconductor lasers, quantum dash lasers, long-term stabilization.

“…In addition, there are special optical fibers used instead of the single-mode fiber G.6552D to avoid the chromatic dispersion. They are called dispersion-shifted fiber (DSF) [21] or dispersion compensated fiber (DCF) [22]. These solutions are also not compatible with 5G mobile and wireless networks because the passive optical networks (PONs) between the central-and base-stations are already places with a standard single-mode fiber.…”

This paper describes and discusses the practical application of an opto-electronic oscillator for the next generation of 5G mobile and wireless networks based on millimeterwave technology. The application of a single-loop, opto-electronic oscillator is designed for 39 GHz and will be implemented in the central-station of an upcoming 5G mobile and wireless network. The aim of this configuration is to decrease the complexity of the base-stations for a next-generation system and provide an economic advantage for upcoming 5G networks. The system is designed to avoid the power penalty due to the chromatic dispersion, is temperature stabilized to have a long-term stability and has a low side-modes effect to ensure a low phase noise.

Our work is devoted to the analysis of a power spectral density (PSD) of amplitude and phase fluctuations of the laser and the laser optoelectronic oscillator (LOEO) with direct modulation. Using the control operator equation of the laser, the amplitude and phase fluctuations of the laser covered by positive optoelectronic feedback were analyzed for the two-level model. Systems of differential stochastic equations of laser and LOEO are compiled, and analytical dependencies of spectral power density of amplitude and phase fluctuations in approximation of small phase noise are determined. The obtained design relationships were compared with experimental PSD of amplitude and phase fluctuations of the laser and LOEO. Shown to achieve in LOEO, the PSD of phase fluctuations less than −140 dB∕Hz at the F ¼ 10 kHz offset 10 GHz radio frequency (RF) oscillation, it is necessary to use highly coherent laser PSD phase fluctuations less than −100 dB∕Hz at the F ¼ 10 kHz offset and achieve noise reduction by synchronizing the longitudinal laser modes by directly modulating the laser with a harmonic RF signal of LOEO generation. Our results make it possible to construct the theory of LOEO and the coupled LOEO based on a system of operator differential equations of a laser with fluctuations covered by a positive feedback circuit on the variable component of the pumping current.
