Abstract: This study presents a method for fabricating optical filters on the end facet of an optical fiber by depositing multilayer coatings of linear carbon stabilized with silver nanoparticles. A semi-automated film deposition setup is proposed, utilizing a droplet deposition technique for water-based colloidal systems. The transmission spectra of filters with 10, 20, and 30 layers are measured. The results demonstrate that the transmission spectrum narrows as the number of layers increases, with the central spectral region shifting toward a wavelength of 1100 nm. The study demonstrates a fast and technically feasible approach for fabricating optical notch filters on the optical fiber end facet. [ABSTRACT FROM AUTHOR]
