In this paper, the wave dispersion in a light-sensitive liquid crystal elastomer porous phononic crystal is investigated. An opto-mechanical indirect-coupling strategy is proposed to investigate the coupling optovariation of band structures. Firstly, the opto-deformation of the phononic crystals is analyzed, and then the band structures in the deformed lattice is determined. The effects of light intensity and director orientation on the properties of absolute band gaps are discussed. The results show that the absolute band gap structure depends on the light intensity, the angle between the light and the director, as well as the porosity. These unique properties promise prospective applications in the intelligent tuning of band structure in pononnic crystals.
