What are the ways to deposit a 100-200 nm layer of TiO2 thin film on the cross section of the polished end of a single mode optical fiber?

The cut end of an optical fiber at 1550 nm operation reflects 4% of light due to Fresnel boundary due to air and silica glass. I want to increase this by coating TiO2. Apart from ALD approach,...
