Electrojetting is a low cost high throughput method with a very large material flexibility. Furthermore, electrohydrodynamic co-jetted (EHDCJ) fibers expand the possibilities of structure and material variation of standard procedures[1]. The high surface to volume ratio of a jetted fiber makes them excellent competitors for sensing or filtering applications. In photonic applications, the refractive index is a key parameter; but stiffness, diameter and compatibility with the media also play an important role. Fibers with dyes or fluorescent nanoparticles have been shown as light sources and random polymer fiber cavities have been shown.[2] The possibility of developing new photonic sensors, with very narrow spectral resolution, taking advantage of physical and mechanical properties of complex co-jetted fibers is of great interest. We present our advances in the fabrication of complex polymer such as multi-polymer and multi-dye fiber resonators with this technique.
