title: Bend insensitive optical fiber with ultralow bending loss in the visible wavelength band.
abstract: We report experimental development of a single-mode optical fiber optimized for a wavelength band of 400 nm to 700 nm, which showed negligible bending loss of 0.09 dB/loop at 400 nm and 0.23 dB/loop at 633 nm for a loop diameter of 10 mm.
