| Research Abstract |
Refractive index change is induced by the light illumination in the polymer that changes crystal structure with the temperature changing process. The average refractive change of the material is measured by the Spectroscopic Ellipsometry. Space resolved index change is measured by the interferometry. In other approach, using the polymer that coumarin molecules are attached to both end, we changed the refractive index and absorption spectrum by the dimerization and its inverse process with light illumination.
