Abstract
Optical switching properties based on the photochromism of spiropyran-doped DNA-lipid complex films have been studied. On-off switching of the incident light under the alternate excitation of UV- and visible light showed strong dependence of the intensity of the excitation light. We have obtained the switching times of around 200-300ms, but much faster response could be expected since the proportional tendency has not been saturated yet.
