“…Flexibility can be further enhanced if a polarization selection is performed at the NOLM output [39]. For example, assuming circular (say, right) input polarization, and selecting the orthogonal (left) polarization component at the NOLM output (see Figure 1), the NOLM power transmission is given by [40]…”

We propose in this work a technique for determining the amplitude distribution of a wave packet containing a large number of short optical pulses with different amplitudes. The technique takes advantage of the fast response of the optical Kerr effect in a fiber nonlinear optical loop mirror (NOLM). Under some assumptions, the statistics of the pulses can be determined from the energy transfer characteristic of the packet through the NOLM, which can be measured with a low-frequency detection setup. The statistical distribution is retrieved numerically by approximating the solution of a system of nonlinear algebraic equations using the least squares method. The technique is demonstrated numerically in the case of a packet of solitons.

“…[12][13][14]. The flexibility and robustness of such NOLM-based devices with strict polarization control allowed envisioning their use in optical transmission and data processing systems to perform a wide range of essential operations including pedestal removal, all-optical signal regeneration [15][16][17][18][19], even at various wavelengths simultaneously for WDM systems [20] or in the case of complex, multilevel modulation formats (constellations) [21], wavelength conversion for OTDM systems [22], as well as all-optical logic gates [14]. Other noticeable uses of the PI-NOLM include the determination of the temporal profile of ultrashort optical pulses [23], as well as estimating the amplitude statistics of a bunch of optical pulses [24,25], which provided in particular one of the first experimental pieces of evidence of the emergence of ultrashort extreme events (optical rogue waves, ORWs) in noise-like pulses (NLPs) [25].…”

In this work we browse an overview of the complex dynamics that arise in the non-stationary modes of operation of partly mode-locked fiber lasers under strict polarization control. Both ring and figure-eight cavities implementing saturable absorber mechanisms that rely on nonlinear polarization rotation were considered. The use of twisted fiber ensures robust operation, whereas precise polarization adjustments allow tailoring the nonlinear switching characteristic in a clear and repeatable manner. The enhanced flexibility of these sources allowed identifying and studying a broad spectrum of peculiar dynamics, in particular by implementing the temporal and spectral mapping techniques. These include the emergence, fusion, splitting, complex evolution and eventual decay of chaotic bunches of radiation, which are also subject to large spectral shifts, ample quasi-periodic instabilities, extreme-intensity events or the creation of solitons, among others, as well as the complex evolution of massively multiple soliton states. Finally, with the help of numerical simulation, several aspects of the physics underlying these puzzling behaviors could be elucidated.
