Title:
OPTICAL FIBER DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/158091
Kind Code:
A1
Abstract:
To achieve an optical fiber device wherein a loss of light traveling in an optical fiber is suppressed. This optical fiber device is provided with: a light source unit that generates laser light; an optical element to which light outputted from the light source unit is inputted; and a first optical fiber, to which light outputted from the optical element is inputted, and which is capable of leaking the light from a side surface. The incidence angle distribution indicated by light inputted to an input-side end surface of the first optical fiber is wider than the incidence angle distribution indicated by light inputted to an input-side end surface of the optical element.
