The titanium dioxide (TiO2) is a low cost material compared to III-V semiconductors. It handles high power intensities and is non-toxic compared to chalcogenide glasses. It is transparent from the visible to the mid-infrared wavelength of interest in our project. Regarding the nonlinearity, we can expect at least 30 times better than silica . Moreover, it presents no TPA at standard telecommunications wavelength. This is why we believe that the titanium dioxide represents the perfect candidate for the next generation of telecommunication and all-optical processing.
