“…On the other hand, a CROW laser can also lock to the input signal through the process of injection-locking so the input changes the operation of the CROW itself [7,[12][13][14]. Injection-locking can be used to tune the resonance frequency of the array to or away from the central wavelength of an optical pulse to be propagated through the array.…”

We investigate active, electrically pumped coupled-resonator optical waveguides (CROWs) in the form of InP-InGaAsP Fabry-Perot resonator arrays. We discuss the fabrication of these devices and present measurements of the transmission spectra. The signal-to-noise ratio is found to be a strong function of wavelength and degraded rapidly along the resonator chain away from the input. Our results highlight a number of ingredients toward practical implementations loss-compensated and amplifying CROWs.

“…Indeed, the injection locking of semiconductor lasers was shown to significantly improve the coherence properties of the emitted signal, leading for example to the reduction of the mode hopping and mode partition noise [48], the reduction of the laser linewidth [49] and of the frequency chirping [50], and an enhancement of the modulation bandwidth [51][52][53]. For telecommunication purposes, optical injection is for example interesting in the development of semiconductor laser arrays, injection locking has been demonstrated to operate conveniently by synchronizing an array of lasers onto a unique master [54]. Injection locking may also prevent spurious feedback effects which are difficult to avoid and, as shown in the previous section, which may seriously disturb the laser operation.…”

In this paper we summarize the recent results on nonlinear dynamics of vertical-cavity surface-emitting lasers (VCSELs) which are bearing the fingerprints of the particular polarization properties of VCSELs. Due to the surface emission and cylindrical symmetry, VCSELs lack strong polarization anisotropy and may undergo polarization switching and polarization mode-hopping. This provides new specificities to the rich nonlinear dynamics induced in VCSELs by an external perturbation. We unveil both experimentally and theoretically these new specificities for the case of optical feedback, optical injection, and unidirectional synchronization between VCSELs.

“…It can be used for reduction of the laser linewidth [12] and the mode partition noise 2 Advances in Optical Technologies [13] or for an enhancement of the modulation bandwidth [14] and for synchronizing an array of lasers onto a unique master [15]. Furthermore, OI dynamics is also of interest from a fundamental point of view and rich dynamics as period doubling route to chaos [16][17][18], resonance tongues [19], and excitability [20] have been reported.…”

Nonlinear dynamics of Vertical-Cavity Surface-Emitting Lasers (VCSELs) induced by optical injection, optical feedback, current modulation and mutual coupling is reviewed. Due to the surface emission and cylindrical symmetry VCSELs lack strong polarization anisotropy and may undergo polarization switching. Furthermore, VCSELs may emit light in multiple transverse modes. These VCSEL properties provide new features to the rich nonlinear dynamics induced by an external perturbation. We demonstrate for the case of orthogonal optical injection that new Hopf bifurcation on a two-polarization-mode solution delimits the injection locking region and that polarization switching and injection locking of first-order transverse mode lead to a new resonance tongue for large positive detunings. Similarly, the underlying polarization mode competition leads to chaoticlike behavior in case of gain switching and the presence of two transverse modes additionally reduces the possibility of regular dynamics. The bistable property of VCSEL makes it possible to investigate very fundamental problems of bistable systems with time-delay, such as the coherence resonance phenomenon. We also demonstrate that the synchronization quality between unidirectionally coupled VCSELs can be significantly enhanced when the feedback-induced chaos in the master laser involves both orthogonal LP fundamental transverse modes.
