Elastomer based electrically tunable, optical microcavities
Abstract
Tunable optical elements are mostly realized by microelectromechanical systems, which require expensive and complex lithography during processing. We demonstrate an alternative device based on an electrically tunable<br/>microcavity employing a dielectric soft elastomer actuator. The cavity resonance is varied by changing the physical cavity thickness due toelectrostriction of the soft elastomer. We realize a tunable metal-elastomerDBR<br/>multi-half wavelength microcavity with a cavity layer thickness around 12 µm and quality factors up to 700. Applying a voltage up to 60 V between bottom ITO and top metal electrode tunes the wavelength of the cavity modes up to ∆λ = 14 nm, which relates to a cavity thickness change of about 200 nm. This<br/>concept allows the implementation of tunable optical elements like tunable filters or resonators with low cost and simple processing.<br/>
