“…The inherent phase noise in the nonlinear P1 oscillation due to the spontaneous emissions harms its applications. For instance, the phase noise can reduce the signal-to-noise ratio in communications [19]. 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].…”

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.

“…Nonlinear dynamical period-one (P1) oscillations in optically injected semiconductor lasers have been actively investigated for photonic microwave generation [1][2][3][4][5][6][7][8][9][10][11][12][13]. Photonic microwave generation enables the transmission of microwave signals over optical fibers with no electromagnetic interference and low propagation loss [14][15][16].…”

“…The P1 oscillation is obtained when a stably locked laser experiences a Hopf bifurcation, which generates a modulation of the laser emission intensity at a microwave frequency [1,13,44]. The P1 oscillation has been investigated in conventional single-mode distributed feedback (DFB) lasers [1,2,[45][46][47], quantum-dash or quantum-dot lasers [5][6][7], as well as vertical-cavity surface-emitting lasers (VCSELs) [3,4,48,49]. Dual-wavelength injection and multi-transverse mode injection have also been reported for generating photonic microwave signals [3,9,50].…”

Phase noise of the period-one (P1) nonlinear dynamical oscillation in an optically injected semiconductor laser is numerically investigated. The P1 dynamics causes the laser output intensity to oscillate at a widely tunable frequency for photonic microwave generation, although the intrinsic spontaneous emission in the laser inevitably degrades the microwave signal and manifests as the oscillation phase noise. To characterize the phase noise, the P1 microwave linewidth is first numerically examined through the rate equations with a Langevin term. The P1 microwave linewidth is found to vary with the injection parameters. It is nearly minimized when the microwave power maximizes. Owing to the laser nonlinearities, the P1 microwave linewidth can even be smaller than the free-running optical linewidth. By adding an optical feedback to the laser, the P1 microwave linewidth is found to reduce as the feedback strength and feedback delay increase, in which an inverse-square dependency is followed asymptotically. By modification to a dual-loop feedback, noisy side peaks around the central P1 frequency are effectively suppressed through the Vernier effect. The dual-loop feedback maintains a low phase noise variance over a wide tuning range of the P1 frequency, while allowing long delay times for significant P1 microwave linewidth narrowing.

“…Interest has primarily focused on the stably locked regime of injection locking [1] and dynamical regimes which produce waveforms exhibiting chaos [2]. Since the mid 2000's the so-called period-one regime/state of injection locking has received increased attention for its ability to generate microwave tones while only requiring steady state biasing and temperature control of the master and slave lasers [3][4] [5].…”
