摘要

本文利用液晶弹性体的光敏特性,提出了一种栅格状声子晶体板,以实现多模波段光调谐。采用间接耦合策略确定声子晶体板的光带变化。首先研究了声子晶体板的自发变形。然后对光变形声子晶体板中的色散进行了研究。并给出了未变形声子晶体板的能带结构进行了比较。详细阐明了晶胞几何尺寸和光强的影响。结果表明,声子晶体板中的能带结构可以通过调节光强来调节,且对单晶几何尺寸有敏感的依赖性。光变形板声子晶体板为光控声子晶体板的设计提供了一种选择,在器件和系统的光学控制中具有广阔的应用前景。

Opto-band tuning in a liquid crystal elastomer phononic crystal plate
Based on the light sensitivity of liquid crystal elastomers, a Grille-like phononic crystal plate is proposed in this paper with the aim to achieve multi-mode band opto-tuning. The indirect coupling strategy is used to determine the opto-band variation in phononic crystal plate. The spontaneous deformation of the phononic crystal plate is firstly investigated. Then the wave dispersion in the opto-deformed phononic crystal plate is explored. The band structure in undeformed phononic crystal plate is also given for comparison. The effects of geometrical sizes of unit cells and light intensity are clarified in detail. The result indicates that the band structures in phononic crystal plates can be tuned by adjusting the light intensity, which displays sensitive dependence on the unit cell geometrical sizes. The phononic crystal plate with opto-deformable slabs provides a choice in design of opto-controlling phononic crystal plate, and has prospective applications in optical controlling of devices and systems.

期刊介绍: Wave Motion is devoted to the cross fertilization of ideas, and to stimulating interaction between workers in various research areas in which wave propagation phenomena play a dominant role. The description and analysis of wave propagation phenomena provides a unifying thread connecting diverse areas of engineering and the physical sciences such as acoustics, optics, geophysics, seismology, electromagnetic theory, solid and fluid mechanics. The journal publishes papers on analytical, numerical and experimental methods. Papers that address fundamentally new topics in wave phenomena or develop wave propagation methods for solving direct and inverse problems are of interest to the journal.
