Mechanically Tunable Photonic Crystals

The next frontier in photonic crystal research may be to achieve dynamic tunability that allows real-time, on-demand control of the photonic band structure. Recently, researchers have been working on a new strategy for achieving this goal—by applying mechanical force. This approach can produce much greater tunability than is possible with electro-optic materials and may greatly expand the usefu...

Characterization of a Mechanically Tunable Gyroid Photonic Crystal Inspired by the Butterfly <i>Parides Sesostris</i>

99 wileyonlinelibrary.com C O M M U N IC A IO N geometries. Using the naturally occurring photonic gyroid found in the wing scales of Parides sesostris butterfl ies [ 28 ] as an experimental model system ( Figure 1 ), we employed high-resolution additive manufacturing to replicate its 3D architectural details in a reversibly deformable macro-scale analogue. We specifi cally used a fi lling frac...

Mechanically tunable photonic crystal structure

We report a tunable nanophotonic device concept based on flexible photonic crystal, which is comprised of a periodic array of high-index dielectric material and a low-index flexible polymer. Tunability is achieved by applying mechanical force with nano-/microelectromechanical system actuators. The mechanical stress induces changes in the periodicity of the photonic crystal and consequently modi...
