Highly photosensitive sol-gel derived inorganic 0.2GeO2:0.8SiO2 (germanosilicate) films have been developed to simplify the fabrication of photonic devices using a single step direct UV-imprinting (DUI) technique. The KrF excimer laser (248 nm) light induced refractive index change (?n) of germanosi...
