“…Table I lists the parameters used in the simulations in this paper, unless otherwise noted. Using the steadystate solutions found in (6)-(10) and the small-signal response in (12)- (14), we can plot the state variables across the locking range map, as shown in Fig. 1.…”

Abstract-The modulation response of injection-locked lasers has been carefully analyzed, theoretically and experimentally, with a focus on the strong optical injection regime. We derive closed-form solutions to the relaxation oscillation (resonance) frequency and damping term, as well as the low-frequency damping term, and discuss design rules for maximizing resonance frequency and broadband performance. A phasor model is described in order to better explain the enhancement of the resonance frequency. Experimental curves match closely to theory. Record resonance frequency of 72 GHz and broadband results are shown.

“…Full and open diamonds at negative detuning mark the boundaries of a region of bistability between the locked steady state and a periodic orbit (associated with four-wave mixing). This bistability phenomenon was observed in [7] and then it was studied numerically in [8], but the authors did not recognise the underlying bifurcation mechanism. This motivated the asymptotic analysis in [9], which revealed the existence of a torus bifurcation curve for negative detunings.…”

We show how bifurcation theory and experimental measurements can be used hand-in-hand to analyse transitions to complicated dynamics in a semiconductor laser subject to optical injection. By a direct comparison of theoretical and experimental optical spectra we identify and explain the underlying dynamics in phase space. This is demonstrated with four distinct bifurcation transitions, including a transition near a saddle-node Hopf point and an intermittent transition to chaos.

“…However, external injection is advantageous in comparison to self-seeding, in that it does not require any adjustment of the repetition frequency or external cavity length. Furthermore, the possibility of being able to improve laser the bandwidth and reduce the chirp has resulted in injection locking of semiconductor lasers being actively investigated over the past decade [22]- [25].…”

An analysis of optical injection on a gain-switched DFB laser and its impact on pulse parameters that influence the performance of the pulse source in high-speed optical communication systems is presented in this paper. A range of 10 GHz in detuning and 5 dB in injected power has been experimentally identified to attain pulses, from an the optically injected gain-switched DFB laser, with durations below 10 ps and pedestal suppression higher than 35 dB. These pulse features are associated with an SMSR of about 30 dB and a timing jitter of less than 1 ps. This demonstrates the feasibility of using optical injection in conjunction with appropriate pulse compression schemes for developing an optimized and cost-efficient pulse source, based on a gain-switched DFB laser, for high-speed photonic systems.
