|Title:||An investigation into the fundamentals of trapping and sensing in microstructured photonic crystal fibers||Authors:||Shinoj Vengalathunadakal Kuttinarayanan.||Keywords:||DRNTU::Science::Biological sciences::Biophysics||Issue Date:||2012||Source:||Shinoj, V. K. (2012). An investigation into the fundamentals of trapping and sensing in microstructured photonic crystal fibers. Doctoral thesis, Nanyang Technological University, Singapore.||Abstract:||Ultra sensitive optical manipulation and detection techniques employing specialty fiber optics and tailor made coherent lasers have huge potential in research and development of new generation medical diagnosis systems. Photonic crystal fiber (PCF) is one such specialty fiber that has emerged prominent in recent years and has found to be an efficient medium for sensing or other micro manipulation such as optical trapping or tweezing and promises a noninvasive, non-contact methodology with minimum damage to the living cells. A hollow-core PCF (HC-PCF) can achieve guidance in air by using the Bragg reflection from the periodic fiber cladding structure, and has the potential of being a medium for efficient biosensing application due to the increased light-matter interaction in the hollow-core.In this perspective, the main objective of the thesis focuses on the research and development of relevant concepts and optical system configuration for: u detection of target analytes/particles from an extremely low fluorescent sample volume using such microstructured fibers, and u multifunctional analysis system to perform optical trapping, position sensing, and spectral characterization sequentially and simultaneously.||URI:||http://hdl.handle.net/10356/49896||Fulltext Permission:||open||Fulltext Availability:||With Fulltext|
