Micro-nano polymer optical fiber probe, preparation and application

In the national 863 project "key technology" farmland environment perception, national science and technology support project "rural environment monitoring and landscape construction key technology research", the national natural science fund project "fluorescent tags tubular photonic crystal fiber array for on-line detection of heavy metal ions such as support, recently, the Chinese academy of sciences hefei smart intelligent information centres chang material science research institute researcher and Ceng Xinhua associate professor micro-nano polymer optical fiber probe, led the team in the important progress in applied research.

Team used in single mode and multimode laser single core fiber, multi-fiber on controlled assembly micro-nano optical fiber array structure, preparation of a series of polymer optical fiber probe micro-nano structure. Including: obtain 50 nm curvature radius of the polymer structure of probe, work is very suitable for near-field optics; Optical fiber polymer lens made of micro/nano level the curvature radius and length of hundreds of microns polymer probe, the optical field parameters for the finite difference time domain (FDTD) numerical simulation and experimental measurement, have very good consistency; Implement multi-mode (complex mode) and multicore polymer on the optical fiber probe array structure of assembly. Team personnel and is applied to the polymer optical fiber probe scanning optical microscope system design, development and characterization of study, relevant results published in a recent issue of optical class international academic journal Optics Express (called Express) (2013, 21 (1) : 30-38)
