Azobenzene dye-doped liquid crystal elastomers (LCE) are known to give strong photomechanical responses. We
review photothermal heating actuated Photomechanical Optical Devices (PODs) and applications to systems by
examining successful attempts at cascading macroscopic PODs in a series configuration. Using these results, we
present some new design strategies that have the potential of miniaturizing these systems with increases in the
response time and system integration.
