The measured results show that for a lens with an appropriate radius, the use of an LPFG would lead to a higher coupling efficiency over a range of long working distances than that obtained without using the LPFG.application/pdf384302 bytesapplication/pdfen-USDiffraction gratings; Gradient index optics; Integrated optics; Light; Optical fiber coupling; Optical instrument lenses; Long period fibre gratings; Mechanical connectors; Optical coupling; Working distances; Single mode fibersjournal article10.1049/el:199902272-s2.0-0032626271http://ntur.lib.ntu.edu.tw/bitstream/246246/200704191001079/1/00757160.pdf
