Reprogrammable electro-chemo-optical devices and methods for using the same
Abstract
Reconfigurable, active optical components can flexibly manipulate light. One example of these components is an electro-chemo-optical device that utilizes a metal oxide film with a complex refractive index that varies as a function of an oxygen vacancy concentration. The optical device may include a metal oxide film, a first electrode, and a second electrode. The first electrode and the second electrode may be used to supply a bias voltage to induce a change in the oxygen vacancy concentration in order to change the optical properties (absorbance, transmittance, and/or reflectance) of the optical device. The magnitude and spatial distribution of the oxygen vacancy concentration may be altered to affect the optical properties of the optical device. In some designs, the optical device may also include an ionic conductor and oxygen source to supply/receive oxygen ions to/from the metal oxide film.
