Lab-on-a-fiber-tip-devices combine the different materials and different configurations (for example photonic structures) to optical fiber tips. We propose, fabricated and experimentally demonstrated a fiber tip device, the 3D polymer photonic structure of Fabry-Perot cavity integrated at the end of the optical fiber. Also, we prepared and experimentally demonstrated a fiber tip device with Bragg reflector integrated at the end of the optical fiber. Both structures, the Bragg’s reflector and the Fabry-Perot cavity, were created in IP Dip polymer cylinder with a diameter like a diameter of an optical fiber which is advantageous for integration. Layers of structures consist a material with refractive index 1.5 and air. In addition, a method of transferring and bonding of a photonic structure at the end of the optical fiber is described. In all investigated interval of wavelengths there is good agreement between measured and calculated reflection spectra.
