Low-loss transmission through tightly bent standard telecommunication fibers

This letter presents a principle of low-loss light transmission through tightly bent standard telecommunication optical fibers. The design is based on selective launching and filtering of the fundamental mode in standard graded index multimode fiber. The proposed system has demonstrated significantly better macrobend tolerance than commercially available bend resistant fibers. � 2000 American Institute of Physics.
