Abstract
We present a polymeric optical phase retarder that is electrically tunable by a dielectric elastomer actuator. The soft material device affords a large tuning range ( at ) combined with high accuracy in optical path length and low drift rate . Furthermore, the phase retarder is not sensitive to polarization, introduces a wavefront distortion , and tolerates high power densities . We show the dynamics for periodic phase modulation and demonstrate a simple drive technique for fast phase stepping. The polymer-based device is inexpensive, easy to fabricate, and its design can be adapted to specific applications.
