Abstract:
An optical fiber splicing structure for contacting a splicing end surface of a first housing in which an end of a first optical fiber is held and a splicing end surface of a second housing in which an end of a second optical fiber is held in a state of co-axial centering on an optical axis of the first optical fiber and an optical axis of the second optical fiber, wherein at least one of the first optical fiber and the second optical fiber is a non-silica-based optical fiber, wherein optical axes of the first and second optical fibers are held in the first and second housings, respectively, at angles &thgr;1 and &thgr;2 (&thgr;1â‰ &thgr;2) from a vertical axis of a boundary surface between the splicing end surfaces, and a relationship between the angles &thgr;1 and &thgr;2 satisfies Snell's law represented by an equation (4) at the time of splicing the first and second optical fibers: sin&it;â€ƒ&it;Î¸1sin&it;â€ƒ&it;Î¸2=n2n1(4)where n1 is a refractive index of the first optical fiber and n2 is a refractive index of the second optical fiber.
