“…A few experimental and theoretical studies have been performed on the quenching of the amplitude of the LFF via a second optical feedback [18] or optical injection from another laser [19]. But detailed information about the phase locking and route to ultimate amplitude death is lacking, which is the crucial point we wish to pay attention to in the present paper in the context of a mutually-coupled laser system [20].…”

We analyse the locking phenomena arising when an external-cavity diode laser is subjected to optical injection from another uncontrolled diode laser. The system stability is investigated as a function of coupled cavity time delay and the optical injection strength. Different regimes, spanning from ‘in-phase locking’ to ‘out-of-phase locking’ with ultimate amplitude death of low-frequency fluctuations/pulsations, are described experimentally as well as numerically for weak to moderate injection. Qualitative agreements between numerically and experimentally observed results for amplitude quenching are shown. Numerical studies describe the shifting of phase-flip bifurcation as the optical injection strength is varied for a particular time delay. Stable phase-locking behaviours, which are desired from the point of view of practical applications, are observed numerically in a wide range of control parameter space.

“…Optical feedback is performed by re-injecting laser emission in external-cavity or by ring-cavity geometries. Hence, numerous theoretical and experimental studies on dynamical regimes in semiconductor lasers with optical feedback by re-injecting laser emission [6][7][8][9] and few numerical studies with ring cavity have been reported [10,11].…”

The investigation of the nonlinear dynamics of a semiconductor laser based on nonlinear optical loop mirror (NOLM) feedback using Ge doped optical fiber was carried out experimentally. Animations of compilations of the output power as a function of time series and phase plane with effects of optical feedback level, carrier current and modulation signal strength are demonstrated as a tool to give insight into the laser dynamics. Different dynamic states, including 2×, 4× multiplication and quasi-periodic and periodic frequency-locked pulsing states extended to chaotic behaviour were observed by varying the parameters of modulated frequency and optical feedback strength. The frequency-locked pulsing states were observed to exhibit a harmonic frequency-locking phenomenon and the pulsing frequency is locked to a harmonic nonlinearity in loop instead of the modulated frequency.

“…They are embedded in the chaotic attractor characterizing the dynamics in phase space. Feedback schemes require real-time measurement of the state of the system and processing of a feedback signal [9,10]. The location of the unstable fixed-point must be determined * s.behnia@iaurmia.ac.ir before control is initiated.…”

Stability control in laser is still an emerging field of research. In this paper the dynamics of External cavity semiconductor lasers (ECSLs) is widely studied applying the methods of chaos physics. The stability is analyzed through plotting the Lyapunov exponent spectra, bifurcation diagrams and time series. The results of the study show that the rich nonlinear dynamics of the electric field intensity (| E | 2 ) includes saddle node bifurcations, periodic, quasi periodic, chaotic and regular pulse packages. The issue of finding the conditions for creating stable domains has been studied. By considering the dynamical pumping current system coupled with laser, a method for the creation of the stable domain has been introduced.
