Paper Abstract
Here we report on preparation of planar optical waveguides based on chitosan (DD=80.5%, MW=500kDa) in different
salt forms, chitosan/gold nanoparticles, chitosan/gold nanoparticles/silica hybrids with layered structure and modification
of Na/K ion-exchange waveguides with thin chitosan/carrageenan multilayers. Chitosan-based optical waveguides with
thickness of 0.5- 1.5 μm were obtained on quartz, glass and MgF2 substrates by spin-coating and dip-coating. For
investigation of optical properties, light (wavelength 632 or 532 nm) was coupled into the planar waveguide via the flint
glass prism using goniometer. A number of modes, effective refractive index, waveguide propagation losses were
determined for all samples in the range of relative humidity 10-99%.
