Abstract
The paper presents the diamond-like carbon (DLC) film as a coating for multimode optical fibre, single-mode optical fibre with long-period grating (LPG) and planar optical waveguides. Thin DLC coatings significantly change sensing elements' properties. Constructed systems can be very sensitive to concentration changes of several chemical solutions (e.g. sodium chloride, calcium chloride and ethylene glycol) due to changes of refractive index of the solutions. The influence of Radio Frequency Plasma Chemical Vapour Deposition (RF PCVD) process parameters on sensitivity is discussed. A novel integrated planar waveguide sensing system with DLC film is presented. The films were analysed morphologically and optically.
