Abstract
An optical coupling device including multiple optical fibers each of which includes at least one core; and a self-forming optical waveguide, wherein the optical fibers are arranged facing each other, and the self-forming optical waveguide is provided between the optical fibers, an end portion of the self-forming optical waveguide is optically connected to the core of each optical fiber, the cores of the optical fibers arranged facing each other are optically connected to each other through the self-forming optical waveguide in a linear shape, optical axis directions of the optical fibers optically connected to each other through the self-forming optical waveguide are parallel with each other, and an end portion of each core is diagonally formed with an inclination angle according to a refractive index of each core and a refractive index of the self-forming optical waveguide.
