Abstract

Chemistry Chemistry, Applied Engineering Engineering, Electrical & Electronic Materials Science Materials Science, Multidisciplinary Optics Physical Sciences Science & Technology Technology
The thermal optical coefficient (TOC) and volume thermal expansion coefficient (TEC or beta) of poly(methyl methacrylate) (PMMA) polymers doped with azobenzene dyes were investigated. A novel approach for determining the TEC has been suggested and a non-linear variation in the TOC with increasing wt% of the dopant has been observed and tentatively explained. In addition, the refractive index (RI) contrast necessary for forming a waveguide was demonstrated to be easily achievable by adding a higher-refractive-index material to the blank polymer.
