Investigation of diamond-like carbon (DLC) film properties deposited with plasma methods (RF PACVD) onto optical fibres

Aim of project
The purpose of the project is uniform deposition (with RF PACVD method) of diamond-like carbon fi lms (DLC) and studies on their properties directly on optical fibre. Parameters of the deposition process have strong influence on the obtained values of refractive index and thickness of films, which are the most interesting parameter from the point of view of their sensing applications. The films deposited onto quartz core of optical fibres will be examined and compared to films simultaneously deposited onto silicon wafers.

Expected results
The obtained analysis will allow to develop modern and highly sensitive optical fibre structures for investigation of chemical compound concentration in liquids.
