We consider phoxonic crystals in relation with their application to photon-phonon interaction. The main interests
of such structures are the possibility to confine simultaneously optical and elastic waves in cavities and waveguides
and to engineer the photonic and phononic dispersion relations of waveguides. A variety of coupling mechanisms
are discussed for exaltation or quenching, including classical photo-elastic coupling as a volume interaction effect,
and couplings introduced by moving boundaries or resonator dimensions.
