Claims

[Scope of utility model registration request]

(1) A single layer of cladding at the end of the optical fiber is chemically or mechanically removed to expose the core, and the fibers are bundled together and integrated by applying heat to the treated end and fusing them together. An optical mixer characterized by its structure.

(2) The optical mixer according to claim (1) of the utility model registration, characterized in that a rad layer having a refractive index smaller than that of the core is re-formed on the fused end portion.
