Polyarylates (PARs) with high glass transition temperature (Tg) are used for photonic device applications. Optical properties are investigated, and it indicates that the PARs show high thermal stability as well as high optical transparency. Electron-beam lithography can be performed using the PAR thin films, and high resolution surface relief gratings are fabricated by direct electron-beam writing technique together with thermal development.
