We develop a theory of the soliton self-frequency shift compensation by the resonant radiation recently observed in photonic crystal fibers. Our approach is based on the calculation of the soliton plus radiation solution of the generalized nonlinear Schrödinger (GNLS) equation and on subsequent use of the adiabatic theory leading to a system of equations governing evolution of the soliton parameters in the presence of the Raman effect and radiation. Our theoretical results are found to be in good agreement with direct numerical modeling of the GNLS equation.

“…A large shock time enables the observation of soliton self-frequency shift in silicabased fibers with short lengths (O(10) cm) and intense pump powers (O(1) kW) [39], while in SiN-based waveguides (not resonators), the Raman effect is not observed [40,41]. However, in microresonators, due to the cavity building (finesse F = D1 κ ≈ O(100 − 1000)), the lightmaterial interaction length is effectively increased (to O(1) m) and meanwhile the pulse peak power is dramatically promoted (e.g.…”

The formation of temporal dissipative solitons in continuous wave laser driven microresonators enables the generation of coherent, broadband and spectrally smooth optical frequency combs as well as femtosecond pulses with compact form factor. Here we report for the first time on the observation of a Raman-induced soliton self-frequency shift for a microresonator soliton. The Raman effect manifests itself in amorphous SiN microresonator based single soliton states by a spectrum that is hyperbolic secant in shape, but whose center is spectrally red-shifted (i.e. offset) from the continuous wave pump laser. The shift is theoretically described by the first order shock term of the material's Raman response, and we infer a Raman shock time of 20 fs for amorphous SiN. Moreover, we observe that the Raman induced frequency shift can lead to a cancellation or overcompensation of the soliton recoil caused by the formation of a (coherent) dispersive wave. The observations are in excellent agreement with numerical simulations based on the Lugiato-Lefever equation (LLE) with a Raman shock term. Our results contribute to the understanding of Kerr frequency combs in the soliton regime, enable to substantially improve the accuracy of modeling and are relevant to the fundamental timing jitter of microresonator solitons.Introduction. -Microresonator based optical frequency combs (Kerr combs) [1, 2] enable optical frequency comb generation from a continuous wave (CW) laser, with repetition rates in the microwave domain (>10 GHz), and broad spectral bandwidth [3][4][5]. Recently, a qualitatively new operation regime has been discovered [6], in which the parametrically generated comb seeds the formation of a temporal dissipative (cavity) soliton [7][8][9]. Such temporal dissipative solitons, first externally induced in fiber cavities [10], have been observed in Kerr frequency comb experiments using crystalline microresonators [6,11] and have recently also been generated in photonic chip based silicon nitride (SiN) integrated resonators [5,12]. Soliton based microresonator frequency combs have several attractive features, in particular being fully coherent, having smooth envelopes and giving access to femtosecond pulses. Indeed, the short duration of temporal solitons in crystalline microresonators have been used for external fiber broadening [6,13] and have allowed to achieve self-referencing (i.e. determination of the comb's carrier envelope frequency) enabling to count the cycles of light [13]. Moreover, taking advantage of dispersion engineering [3,14], the presence of third (and higher) order dispersion allows (coherent) dispersive waves (DWs) to be generated [12] via the effect of soliton induced Cherenkov radiation [15]. This process has been used to create a photonic chip based (coherent) frequency comb in a SiN microresonator spanning 2/3 of an octave at electronically detectable mode spacing. However, while advances in theoretical simulations of the soliton regime have occured [14,16,17] a key underlying question is what ot...

“…Soft-glass photonic-crystal fibers for frequency shifting and white-light spectral superbroadening of femtosecond Cr:forsterite laser pulses Several attractive PCF-based strategies have been demonstrated for highly efficient nonlinear-optical spectral transformation of femtosecond Ti:sapphire laser pulses. These solutions are based on dispersive-wave emission by solitons [77], four-wave mixing [78,79], modulation instabilities [80], stimulated Raman scattering [78], and soliton self-frequency shift [81]. Extension of these strategies of frequency conversion to other input wavelengths and other types of short-pulse sources requires careful PCF dispersion management and sometimes necessitates optimization of the fiber material.…”

Over the past years, photonic-crystal-fiber components and devices have imparted a powerful momentum to the development of femtosecond chromium forsterite laser systems. Fibers of this type allow efficient spectral and temporal transformations of ultrashort light pulses delivered by Cr:forsterite laser sources, enhancing the potential of these lasers as a powerful tool for nanophotonics, biomedical optics, microspectroscopy, telecommunication technologies, semiconductor chip imaging, coherent control, optical metrology, and offering a platform for the creation of an advantageous front end for extreme-intensity laser systems.Supercontinuum generation in a photonic-crystal fiber
