Paper Abstract

Thin films of poly(N-vinylcarbazole) (PVK) were prepared by spincoating upon fused silica substrates. PVK was dissolved in dimethyl formamide (DMF) and processed at elevated temperatures. Thin films with the required thickness and low surface roughness were obtained by careful optimization of the preparation parameters, such as concentration, spinning speed and temperature of these spincoating process. The dispersion of refractive indices of PVk films was measured by reflectometry and by prism coupling at 633 nm and 1064 nm. The attenuation loss of slab waveguides was measured by monitoring the stray light of the guided mode with a diode array. The loss depends significantly on the relative ratio of surface roughness to thickness. As this ratio depends on preparation conditions, we succeeded in fabricating planar waveguides of PVK that had an attenuation loss of only 1 dB/cm at 633 nm.
