Research Abstract

Recently, photonic crystals (PCs) composed of spatially ordered dielectrics with lattice parameters comparable to the wavelength of visible light have received much attention due to their unique properties in controlling the propagation of light. Even those crystals that do not exhibit a complete photonic band gap can still show interesting optical properties, such as an optical stop band that can also be observed as a structural color. It is important to be able to control the photonic band structure through external stimuli for many practical applications. Along this line we prepared tunable photonic band gap crystals by infiltrating photoresponsive liquid crystals into inverse opal structure films. The tuning of their optical properties could be realized by means of photoinduced phase transition of liquid crystals. The photoinduced phase transition behavior could be evaluated by measuring the change in their optical properties under light irradiation, and it was clearly observed that the behavior varied with temperature and light intensity. The materials could store and display images that were created by the irradiation with LTV light through a photomask. A great advantage of this technique is that the films themselves can display an image without the use of polarizers or other assistant materials, and they can also render a color display that can be selected by varying the lattice distance of the inverse opal structure. In addition, we achieved the control of their optical properties by the application of an electric field. Because the state induced by the electric field is different from that engendered by a photoinduced phase transition, it is now possible to switch among three states by a combination of these two techniques. The materials that we have developed have possibilities for practical applications in optical devices.
