Abstract
Provided is a low-loss mode scrambler in which a steady mode distribution can be obtained in a short distance and switch to an entire mode distribution state is easy even when incident light is smaller than a numerical aperture of a fiber to be measured in a multimode fiber having a core diameter exceeding several tens of μm and a numerical aperture of 0.2 or more. One fiberis wound around a plurality of bobbinsandhaving a radius larger than a minimum bending radius of the fiber to form a bundle, and the fiberis twisted by rotating the bobbinsandto form a twisted portion, whereby it is possible to perform output of a steady mode from light incident on the fiber
