Recent Progress in Polymer Optical Fiber Light Sources and Fiber Bragg Gratings

Research directed toward polymer optical fiber light source generation and polymer optical fiber Bragg gratings to be part of a novel all-polymer sensor system, integrating a light source with a sensor, are reported. It is demonstrated that photo generated fluorescence can be detected 2 m away from the excitation point using a novel fiber design. Furthermore, the research works focused on polymer fiber sensors have proven that Diphenyl Sulfide + Trans-4-stilbenemethanol, which is a core composition used by numerous groups, exhibited very good photosensitivity, allowing FBG inscription.
