“…Recent studies indicate that multiphonon AO interaction could survive and be observable in multilayer structures [66] even in the presence of realistic material losses. Multilayer phoxonic cavities have been also considered for modulation of light emission via AO interaction [67]. The enhanced light extraction achieved by placing emitters inside optical cavities can be combined with efficient modulation through a resonating elastic wave.…”

Abstract:The interaction of light and sound waves at the micro and nanoscale has attracted considerable interest in recent years. The main reason is that this interaction is responsible for a wide variety of intriguing physical phenomena, ranging from the laser-induced cooling of a micromechanical resonator down to its ground state to the management of the speed of guided light pulses by exciting sound waves. A common feature of all these phenomena is the feasibility to tightly confine photons and phonons of similar wavelengths in a very small volume. Amongst the different structures that enable such confinement, optomechanical or phoxonic crystals, which are periodic structures displaying forbidden frequency band gaps for light and sound waves, have revealed themselves as the most appropriate candidates to host nanoscale structures where the light-sound interaction can be boosted. In this review, we describe the theoretical tools that allow the modeling of the interaction between photons and acoustic phonons in nanoscale structures, namely cavities and waveguides, with special emphasis in phoxonic crystal structures. First, we start by summarizing the different optomechanical or phoxonic crystal structures proposed so far and discuss their main advantages and limitations. Then, we describe the different mechanisms that make light interact with sound, and show how to treat them from a theoretical point of view. We then illustrate the different photon-phonon interaction processes with numerical simulations in realistic phoxonic cavities and waveguides. Finally, we introduce some possible applications which can take enormous benefit from the enhanced interaction between light and sound at the nanoscale.

“…An interesting realization of composite structure is a periodic arrangement of the constituent materials. Periodic structures combining the properties of different artificial crystals-photonic and plasmonic, [27][28][29][30] photonic and phononic (named optomechanical and phoxonic crystals [31][32][33][34][35][36][37], or magnonic and phononic 38,39 -have been investigated in a number of recent papers and for various applications. 37 However, all these publications consider only the propagation of SWs or EMWs or acoustic waves in separate spectral regimes.…”

We investigate the properties of a photonic-magnonic crystal, a complex multifunctional one-dimensional structure with magnonic and photonic band gaps in the GHz and PHz frequency ranges for spin waves and light, respectively. The system consists of periodically distributed dielectric magnetic slabs of yttrium iron garnet and nonmagnetic spacers with an internal structure of alternating TiO2 and SiO2 layers which form finite-size dielectric photonic crystals. We show that the spin-wave coupling between the magnetic layers, and thus the formation of the magnonic band structure, necessitates a nonzero in-plane component of the spin-wave wave vector. A more complex structure perceived by light is evidenced by the photonic miniband structure and the transmission spectra in which we have observed transmission peaks related to the repetition of the magnetic slabs in the frequency ranges corresponding to the photonic band gaps of the TiO2/SiO2 stack. Moreover, we show that these modes split to very high sharp (a few THz wide) subpeaks in the transmittance spectra. The proposed novel multifunctional artificial crystals can have interesting applications and be used for creating common resonant cavities for spin waves and light to enhance the mutual influence between them.

“…In practice, this translates in calculating the relevant optical scattering amplitudes at a sequence of frozen snapshots of the spin wave, during a period, and, at the end of the calculation, obtain the frequency-domain response by Fourier transform. 33,36 A similar approach was also successfully applied to analyze acousto-optic interaction effects in corresponding phoxonic cavities, [43][44][45][46] encompassing both weak-and strong-coupling regimes and recovering the results of the widely employed linear photoelastic model in the weak-coupling limit. 46 However, the quasistatic adiabatic approximation has a number of drawbacks, which may be more likely manifested in the case of a spin instead of an acoustic pump wave because the former can attain higher frequencies without being strongly attenuated.…”

A fully dynamic theoretical approach to layered optomagnonic structures, based on a time-Floquet scattering-matrix method, is developed. Its applicability is demonstrated on a simple design of a dual photonic-magnonic cavity, formed by sandwiching a magnetic garnet thin film between two dielectric Bragg mirrors, subject to continuous excitation of a perpendicular standing spin wave. Some remarkable phenomena, including nonlinear photon-magnon interaction effects and enhanced inelastic light scattering in the strong-coupling regime, fulfilling a triple-resonance condition, are analyzed and the limitations of the quasi-static adiabatic approximation are established.
