The subwavelength gratings (SG) were fabricated from electroactive polymers, and prepared to an electrochromic (EC) device. The EC electrode was prepared by the micromolding in capillaries method (MIMIC) process, using P3HT which changes color from red to transparent blue and P(ProDOT-Ph), which undergo a color change from yellow transparent blue upon the application of positive bias. The optics required for SGs are simpler since they show only zeroth-order diffraction. The refractive index of the electroactive polymers were changed in different electrochemical status. Under the illumination of a white light, the diffracted light intensity was reversibly switched by applying different applied potential at a given angle of incidence. On the other hand, by changing the incident angle, various diffraction colors were generated. |
