Basic prerequisites for limit-cycle oscillations within a synchronously pumped passive optical nonlinear fiber-ring resonator

et al. 2011

By taking into account Kerr nonlinearity and negative second-order dispersion, we show by numerical investigations that in a passive optical nonlinear fiber ring resonator synchronously pumped with femtosecond pulses a temporal delay via a resonator length detuning or via third-order dispersion leads to limit cycle behavior, which is represented by an oscillatory evolution of the temporal as well as the spectral pulse shape. By introducing a two-dimensional iterative map, we show that limit cycles arise due to the mutual coupling of different spectral pulse components. The resulting system behavior can be used to introduce additional adjustable frequency components into frequency combs.

Interplay of Polarization and Time-Reversal Symmetry Breaking in Synchronously Pumped Ring Resonators

et al. 2019

Optically induced breaking of symmetries plays an important role in nonlinear photonics, with applications ranging from optical switching in integrated photonic circuits to soliton generation in ring lasers. In this work we study for the first time the interplay of two types of spontaneous symmetry breaking that can occur simultaneously in optical ring resonators. Specifically we investigate a ring resonator (e.g. a fiber loop resonator or whispering gallery microresonator) that is synchronously pumped with short pulses of light. In this system we numerically study the interplay and transition between regimes of temporal symmetry breaking (in which pulses in the resonator either run ahead or behind the seed pulses) and polarization symmetry breaking (in which the resonator spontaneously generates elliptically polarized light out of linearly polarized seed pulses). We find ranges of pump parameters for which each symmetry breaking can be independently observed, but also a regime in which a dynamical interplay takes place. Besides the fundamentally interesting physics of the interplay of different types of symmetry breaking, our work contributes to a better understanding of the nonlinear dynamics of optical ring cavities which are of interest for future applications including all-optical logic gates, synchronously pumped optical frequency comb generation, and resonator-based sensor technologies.Passive nonlinear optical cavities have been studied extensively in the past decades, partly for their ability to increase the efficiency of light-matter interactions through a large enhancement of circulating power [1]. Quite recently, the interest was renewed after the first observation of so-called cavity solitons (stable pulses of light circulating inside a resonator indefinitely) in macro-scaled fiber loops [2] and microresonators [3], underpinning the generation of Kerr frequency combs [4]. In a number of practical studies, such systems are not driven by a continous wave (cw) laser but rather pumped by a train of pulses so that comparatively greater input peak powers are achieved [5][6][7] or to generate solitons and frequency combs with an improved efficiency [8]. This however requires a rigorous control of either the pulse train repetition rate or cavity length to ensure the synchronicity of the pumping, the lack of which might alter the dynamics of the system [9,10].Several studies have focussed on a scenario where the input pulses are Gaussian and their duration is longer than that of a typical cavity soliton. In that case, it has been observed that, provided that the resonator exhibits anomalous dispersion, the peak of the intracavity pulse does not necessarily lock at an extremum of the input power (symmetric solution). Instead, a solution where the peak of the soliton is shifted with respect to the extremum seems to be favoured. This phenomenon is referred to as a spontaneous symmetry breaking of the temporal pulse profile [11][12][13][14] and has been very recently identified in the context of cavity soliton dy...

The spectral analysis of the device (instrument) operators, as an alternative approach to the dynamical polarization phenomena, is presented by means of an example of a classical time-varying optical device, the electrooptical modulator with longitudinal e ect in crystals of KDP type. The polarization-spectral structure of the modulated light is analysed on this basis, both in terms of spectral Jones vectors and of spectral polarization matrices. Some experimental results are presented. IntroductionIn the last few years dynamical polarization phenomena have been studied intensively in di erent branches of optics. Spontaneous pulsation and polarization multistability resulting from the nonlinear interaction of the standing waves with the active medium in gas lasers with weakly anisotropic cavities have been studied at di erent cavity anisotropies with and without an axial magnetic ®eld applied to the active medium [1,2]. Nonlinear dynamics of lasers at intracavity modulation of polarization was analysed [3]. Various polarization handling methods were elaborated, in connection with the needs of optical transmission of information [4]. The use of bistable elements based on polarization dynamics for optical storage devices and ultra-high bit-rate ®bre communication systems was proposed [5]. Various types of rotating element ellipsometers [6] have been described and the real-time ellipsometry was developed on this basis. Polarization-modulation ellipsometry has been developed, where the optical components remain ®xed and the state of polarization of the incident beam is modulated [7].Time-varying Jones and Stokes vectors were introduced in analysing the polarization dynamics phenomena [3, 8±10] and the time evolution of the state of optical polarization (SOP) in the output of anisotropic lasers [1,3,8,9] and optical modulators [10±13] was analysed in these terms.To complement this, a spectral analysis of the time-varying SOPs was performed. The polarization-spectral content of the anisotropic laser output [1,3,9], or of the emerging light from some electro-optical modulators [10] was discussed and the homodyne (beat-signal) spectrum of the output light was displayed [10±14].As a new theoretical approach to the topic of polarization dynamics, Fourier analysis was applied to time-varying Jones vectors and time-varying polarization
