in National Fiber Optic Engineers Conference,
OSA Technical Digest
(Optical Society of America, 2012), paper JW2A.19.
A new functionality of air holes, reduction of micro-bending loss, was analyzed and discussed. The optimum air-hole diameter arranged around the fiber edge to minimize micro-bending loss was also investigated.
