“…[83][84][85]. Forward Brillouin scattering has also found several applications, for example in using transverse modes for passive laser mode-locking [86][87][88][89], sensing [70][71][72]90], Brillouin lasing [8,91] and emitter-receiver schemes [92].…”

Brillouin scattering is an important and interesting nonlinear effect involving the interaction between optical and acoustic fields in optical waveguides. It is increasingly useful in the field of photonics, where it supplies a tunable ultra-narrow linewidth response that can be used for applications including sensing, filtering, and lasing, as well as the acoustic storage of optical pulses. This tutorial gives an overview of the fundamentals of Brillouin scattering aimed at newcomers to the field, and covers the physics underlying the interaction, the mathematical theory, and setup details of foundational Brillouin experiments.

“…The long interaction lengths and power handling in fiber optics allows for complex interplay of FBS with other nonlinearities and often result in cascaded dynamics. Extreme examples of this are lasers that are passively mode-locked at the acoustic resonance frequency [36,37]. It should be stressed that in the case of a straight dispersionless waveguide and for strict intra-mode scattering the intensity variations at the end of a waveguide do not differ from those at the front, because the beat of the pump and Stokes lines and among the Stokes lines vanishes exactly.…”

AbstractInelastic scattering processes such as Brillouin scattering can often function in cascaded regimes and this is likely to occur in certain integrated opto-acoustic devices. We develop a Hamiltonian formalism for cascaded Brillouin scattering valid for both quantum and classical regimes. By regarding Brillouin scattering as the interaction of a single acoustic envelope and a single optical envelope that covers all Stokes and anti-Stokes orders, we obtain a compact model that is well suited for numerical implementation, extension to include other optical nonlinearities or short pulses, and application in the quantum-optics domain. We then theoretically analyze intra-mode forward Brillouin scattering (FBS) for arbitrary waveguides with and without optical dispersion. In the absence of optical dispersion, we find an exact analytical solution. With a perturbative approach, we furthermore solve the case of weak optical dispersion. Our work leads to several key results on intra-mode FBS. For negligible dispersion, we show that cascaded intra-mode FBS results in a pure phase modulation and discuss how this necessitates specific experimental methods for the observation of fiber-based and integrated FBS. Further, we discuss how the descriptions that have been established in these two classes of waveguides connect to each other and to the broader context of cavity opto-mechanics and Raman scattering. Finally, we draw an unexpected striking similarity between FBS and discrete diffraction phenomena in waveguide arrays, which makes FBS an interesting candidate for future research in quantum-optics.

“…Furthermore, the optoacoustic interactions in standard single-mode fiber are significant over the AR frequency range of several tens to hundreds of MHz, which in some cases acts as a limiting factor of the repetition rate of harmonic mode-locking up to hundreds of MHz [3,4,15]. It has been recently demonstrated that the use of gigahertz ARs tightly confined in the micron-sized core of photonic crystal fiber can solve this issue, stabilizing the harmonically mode-locked pulse train at the repetition rate beyond 1 GHz [16][17][18]. The formation of pulse bunches and bound pulse states via the optoacoustic inter-pulse coupling has also been investigated [19][20][21][22].…”

Tailoring of multi-pulse dynamics in mode-locked laser via optoacoustic manipulation of quasi-continuous-wave background

A variety of nonequilibrium multi-pulse states can emerge in a mode-locked laser through the interactions between the quasi-continuous-wave background (qCWB) and optical pulses inside the laser cavity. However, they have been long regarded as unpredictable and hardly controllable due to the noise-like nature of the qCWB, and relevant previous studies thus lack a clear understanding of their underlying mechanisms. Here, we demonstrate that the qCWB landscape can be manipulated via optoacoustically mediated interactions between the qCWB and mode-locked pulses, which dramatically alters the behaviors of multi-pulse dynamics in unprecedented manners. In this process, impulsive qCWB modulations are created at well-defined temporal locations, which act as the point emitters and attractive potentials for drifting pulse bunches and soliton rains. Hence, we can transport a single pulse bunch from a certain temporal position to another on the qCWB, and also make the soliton rain created and collided exclusively at specific temporal locations, in sharp contrast to the conventional cases. Our study opens up new possibilities to control the nonequilibrium multi-pulse phenomena precisely in the time domain, which would not only help the observation and clear understanding of undiscovered features of multi-pulse dynamics but offer a practical means of advanced optical information processing.
