Cascading of Liquid Crystal Elastomer Photomechanical Optical Devices

Abstract

Photomechanical actuation is demonstrated in two coupled liquid crystal elastomer photomechanical optical devices (PODs) acting in series. The response function of an individual POD is characterized and used to predict the temporal response of the coupled system. The predicted coupled-system response agrees with the experiment for several waveforms and frequencies, suggesting that large-scale integration of photomechanical devices is possible.Comment: 4 pages, 4 figures, 1 tabl
