We present a simple system for coating cylindrical devices for photonic related applications based on a wire coating method. Characterization of the system was done using two different polymeric materials, silicon-based PDMS and an acrylate-based polymer, obtaining different coating thicknesses upon varying the parameters of the process. Layers with controlled thickness ranging from hundreds of nanometers to 1 mm can be readily applied over devices with different diameters. We demonstrate the system capabilities for coating tapered optical fibers and glass capillaries. The fabrication of a tunable fused fiber coupler with a photoresponsive polymer layer is also demonstrated. © 2014 IEEE.
