Stretch tuning of Debye ring for 2D photonic crystal covered on dielectric elastomer membrane

Abstract

The tunable diffracted pattern (Debye ring) of the well-ordered closed-packed 2D photonic crystal (PC) is achieved via large deformation of dielectric elastomer (DE) membrane for the first time. Two deformation models are proposed, the in-plane deformation driven by voltage, and the out-of-plane deformation actuated by pressure. Both experiment and theoretical analyses are conducted to explore the tunability of DE stretch on Debye ring of the 2D PC, by voltage and pressure. An excellent agreement is found between the experimental and analytical results. This study shows that tuning the size of Debye ring by voltage driven in-plane deformation is easy to operate and space-saving. However, it needs a high voltage and the adjustable range is relatively small. On the other hand, the pneumatic tuning by out-of-plane deformation has a widely-adjustable range compared with the electric one and the pressure needed is only hundreds to less than two thousands Pascal, which is energy-saving. This work may pave the way for the design of various smart sensors and soft displays with the combination of PCs and DEs.
