“…Upon a further increase in the optical feedback ratio, the linewidth increases again. This variation trend is different from that in the DFB laser and VCSEL [28,35] but is similar to that in the DFB laser with filter feedback at some frequency detuning [45]. The relationship between the phase noise and the feedback ratio is similar to that of the linewidth.…”

“…Therefore, further reduction of the generated microwave linewidth in the DM laser will be undertaken in our next investigation. In addition, the relationship between the linewidth of the generated microwave and the feedback strength in an optically injected semiconductor laser subject to filtered optical feedback is related to the injection parameters [45], so it is worth further studying the relationship between the linewidth and the feedback strength in the DM laser at other injection parameters.…”

In this paper, microwave photonic signal generation based on the period-one dynamic of optically injected discrete mode (DM) semiconductor lasers has been experimentally demonstrated and numerically simulated. The results show that the frequency of the generated microwave increases linearly with the frequency detuning or optical injection ratio. In addition, a single optical feedback loop is sufficient to reduce the microwave linewidth without significantly deteriorating side mode suppression. The simulation results using a model considering the nonlinear dependencies of the carrier recombination agree well with the experimental results, which indicates that the nonlinear carrier recombination effect is important in determining the nonlinear dynamics of optically injected DM lasers.

“…The phase noise can also increase the linewidth of the generated microwave, which affects the performance in radio over fiber (RoF) applications and the maximum detection range in Doppler velocimeters [20], [21]. To solve this problem, many methods have been introduced, such as using double-locking with a microwave source [12], [22], [23], optoelectronic feedback [24], [25] and optical feedback [9], [26]- [28]. Among all of these schemes, optical feedback is a simple and low-cost method to reduce the phase noise and linewidth.…”

Characteristics of microwave photonic signal generation based on P1 dynamic in an optically injected vertical-cavity surface-emitting laser are studied systematically. The evolutions of the linewidth, power and second harmonic ratio of the generated microwave are investigated as a function of injection strength and frequency detuning. The effect of optical feedback on the linewidth and the phase noise of the generated microwave photonic signal is also studied in detail. With the help of optical feedback, the linewidth can be effectively reduced by increasing the feedback strength and feedback delay time. However, there is an optimal feedback delay time to minimize the phase noise.

“…Under certain external settings (e.g., increasing the OF strength), the system leaves the stable state, then period-one oscillation can be invoked through the Hopf-bifurcation and accompanied by an undamped relaxation oscillation [5]. The period-one oscillation produces an intensity-modulated optical wave and gives regular pulsation at microwave frequencies [6][7][8][9]. Period-one oscillation has been found in many significant applications, such as the generation of microwave/millimeter-waves [10], photonic microwave sensing/radar [11,12], radio-over-fiber systems [13,14], and other optical signal processing applications [15,16].…”

In this study, a novel distance sensing method is presented by using a semiconductor laser (SL) with optical feedback (OF) and operating the SL at a switching status happened between two nonlinear dynamic states (stable state and period-one state). In this case, without the need for any electronic or optical modulation devices, the laser intensity can be modulated in a square wave form due to the switching via utilizing the inherent SL dynamics. The periodicity in the switching enables us to develop a new approach for long-distance sensing compared to other SL with OF-based distance measurement systems and lift the relevant restrictions that existed in the systems. Moreover, the impact of system controllable parameters on the duty cycle of the square wave signals generated was investigated on how to maintain the proposed system robustly operating at the switching status. Both simulation and experiment verified the proposed sensing approach.
