Instructions for use Title Design and characterization of single-mode holey fibers with low bending losses Author ( s )

As the fiber-to-the-home network construction increased, optical fiber cables are demanded to be easier to handle and require less space. Under this situation, a single mode fiber (SMF) permitting small bending radius is strongly requested. In this paper, we propose and demonstrate a novel type of bending-insensitive single-mode holey fiber which has a doped core and two layers of holes with different air-hole diameters. The fiber has a mode field diameter of 9.3 µm at 1.55 µm and a cutoff wavelength below 1.1 µm, and shows a bending loss of 0.011 dB/turn at 1.55 µm for bending radius of 5 mm and a low splice loss of 0.08 dB per fusion-splicing to a conventional SMF.
