“…In these reported results, one can see that both theoretical model and experimental studies are intensively presented to observe the rich nonlinear behaviors including the periodic, quasi-periodic, and chaotic phenomena by judiciously adjusting the strengths of external injections and/or optical feedbacks. The achieved dynamical results are widely used to perform the photonic microwave signals [8,9], secure optical communications [10], optical switching [11], radar [12], all-optical AM-to-FM conversion [13], and radio-over-fiber links [14]. Generally, the conventional quantum well laser has a large line width enhancement factor that results in the large chaotic region with the change of external injection or feedback level [15].…”

In this study, the research on the nonlinear dynamics of semiconductor quantum dot laser with two time-delayed optical feedbacks is numerically investigated. Results show that the nonlinear dynamics behaviors of the laser are very sensitive to the rich system parameters in which both feedback strength and bias current are easily controlled to significantly influence the nonlinear dynamics including the periodic state and chaotic state. By judiciously adjusting the bias current of the laser or the feedback strength in the external cavity, period one, period doubling, quasi-period, and chaos are achieved. The feedback levelrelated bifurcation diagrams are analyzed in detail while fixing another feedback level at a constant or varying the bias current. In addition, the translation variables of the 0-1 test method that are clearly bounded for regular behavior and exhibit the Brownian motion for irregular phenomenon are adopted to further evaluate the periodic state and the chaotic state. These results can give insight into the quantum dot laser-based applications in various optical technologies.

“…In this case, tunability to 10 GHz in the microwave frequency can be achieved by control of various components in the external feedback loop. In [13], optoelectronic feedback on a phase modulator, in a optically injected system with many other components is demonstrated to produce a tunable oscillation from 10-46 GHz with the best phase noise -105 dBc/Hz at 10 kHz.…”

The stabilization of a relatively simple microwave oscillator tunable across the full X-band based on a laser subjected to optical feedback is achieved. Specifically, a resonance effect based on locking the two inherent dynamic frequencies of the system, as well as optoelectronic feedback are utilized to achieve a sub-ps jitter and typical phase noise in the range of −107 dBc/Hz at 10 kHz offset from an oscillation frequency that can be tuned from 5.5 to 12.1 GHz. Further, the microwave signal is extracted from the laser-diode injection terminals and eliminates the need for multiple lasers, radio-frequency filters, and external RF sources. This architecture therefore realizes a compact and low-cost microwave photonic oscillator.

“…In this Letter, we demonstrate an approach to enhance the performance of a tunable OEO by subharmonic microwave modulation. The OEO is established based on the period-one (P1) dynamics of an optically injected semiconductor laser [10][11][12][13][14][15]. By changing the optical injection strength, its oscillation frequency can be tuned in the range of 8.87 to 18.41 GHz.…”

“…To narrow the linewidth, a method of optical feedback has been demonstrated, which generated microwave signals up to 45.4 GHz with a linewidth around 10 kHz [13,14]. In order to further reduce the linewidth and phase noise, an optoelectronic feedback loop is applied to construct an OEO [15]. In this system, a portion of the optical output after the CIR is delayed by a span of fiber and then sent to a PD.…”

An approach to enhancing the performance of an opticallyinjected-semiconductor-laser-based optoelectronic oscillator (OEO) is proposed by subharmonic microwave modulation. A free-running OEO is first established based on period-one dynamics of an optically injected semiconductor laser. The oscillation frequency can be tuned in the range of 8.87 to 18.41 GHz by controlling the injection strength, but the output signal suffers from strong side modes and poor frequency stability. To address these problems, subharmonic microwave modulation is applied to the injected semiconductor laser. In the experiment, microwave modulation with 1/2, 1/4, and 1/6 subharmonics is demonstrated. The side-mode suppression ratio is improved by over 40 dB, while the phase noise at a 1 kHz offset is reduced by about 18 dB. Furthermore, the frequency drift over a period of 20 min, which characterizes the long-term stability, is reduced from 8.7 kHz to less than 1 Hz, indicating a significant reduction of over three orders.
