摘要： PROBLEM TO BE SOLVED: To provide an optical fiber light guide device which efficiently receives incident light and guides it.
SOLUTION: A plurality of optical fibers (the diameter of the outer circumference of the core is 980 μm, the diameter of the outer circumference of the clad is 1,000 μm) are ground to a tapered shape so that the ground surfaces cross the axial direction with an angle of 0.19 degree and further cross the core part of an incidence surface. Here, the plurality of optical fibers are ground so that the two intersection lines of the incidence surface and the ground surfaces are mutually parallel and the length of each intersection lines at the core part is 700 μm. A light receiving surface is formed by arranging the incidence surface of the optical fibers thus ground in a line and approximately on the same plane, superposing the ground surfaces of the adjacent optical fibers and fixing the fibers.
