Rodríguez Física, Astronomía y Matemáticas optical waveguides Photochromic polymers photoinduced refractive index Photoinduced refractive index and absorption anisotropies in thin films of an azo dye polymer have been carried out by pump-probe experiments. A refractive index change of Δn=-0.04 was obtained by independently measuring the two indices, parallel and perpendicular to pump light polarization. A long-term stability of the induced birefringence and a reversible photoinduced memory effect have been observed. The experimental results cannot be completely explained by the proposed photoisomerization models to describe the process involved. 2006 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57065006 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
