“…From another point of view, the modulation induced by the acoustic wave is equivalent to a time-varying photonic crystal [2] which, however, can be described in the quasistatic approximation since the period of the acoustic field is much longer than that of the light wave [3][4][5]. Modulating appropriately designed photonic structures with bulk or surface acoustic waves provides further possibilities for tailoring the AO interaction and observing new and potentially useful effects [6][7][8].…”

The limits of validity of the linear photoelastic model are investigated in a one-dimensional dual photonic-phononic cavity, formed by alternating layers of a chalcogenide glass and a polymer homogeneous and isotropic material, which supports both optical and acoustic resonant modes localized in the same region. It is shown that the linear-response regime breaks down when either the acoustic excitation increases or the first-order acousto-optic interaction coupling element vanishes by symmetry, giving rise to the manifestation of multiphonon absorption and emission processes by a photon. Our results provide a consistent interpretation of different aspects of the underlying physics relating to nonlinear acousto-optic interactions that can occur in such cavities.

“…Recently, Qian et al studied AO interaction in 1-D photonic crystals with defects using the transfer matrix method. 28 Psarobas et al reported enhancement of AO interaction using 1-D phoxonic crystals. 29 By inserting defect layers to serve as a cavity in a 1-D phoxonic crystal for optical and acoustic waves, they obtained enhanced modulation of transmitted optical waves when the optical and acoustic modes are simultaneous at the resonance states, leading to efficient AO interaction in a narrow optical band.…”

Because of dual photonic and phononic band gaps generated in the phoxonic crystal, optical waves and acoustic modes can be guided and amplified, respectively, along the line defect that serves simultaneously as an optical waveguide and acoustic wave cavity. By means of finite-element analysis, we show that the confinement of the optical waves and acoustic modes in the same region of space (i.e., in the defect) leads to enhanced modulation of the optical waves by an acoustic cavity mode, and obvious shifts in eigenfrequencies and transmission peaks are observed. Stronger acousto-optic interaction is caused by the amplified acoustic fields and by the long-lifetime interaction of photons and phonons in the line defect. V C 2013 American Institute of Physics.

“…Optical response of layered structures can be altered by the acoustic wave due to spatial variation in the structure. Elastic waves whose particle motion lies in the plane that contains the direction of wave propagation are able to control optical properties of the material [14,15]. These acoustic plate waves are similar to longitudinal waves and their displacement is distributed throughout the entire depth direction in the form of compression and rarefaction.…”

The occurrence of a photonic band gap modulation in the periodic arrangement of a Si-SiO 2 layer, in the presence of in-plane acoustic plate symmetric modes is studied. The proposed structure shows simultaneous existence of photonic band gaps in the infrared region and phononic band gaps in the GHz frequency range. Due to the presence of photonic band gaps and phononic band gaps, this arrangement is called a phoxonic crystal. The optical forbidden band shifted towards lower frequency by acoustooptic interaction. It is also found that the optical forbidden band is increased through an acoustic plate symmetric mode of submicron wavelength in the proposed Si-SiO 2 structure.
