摘要： PURPOSE: An optical fiber grate and optical fiber element using the same is provided to enhance a conversion efficiency between optical modes of an incident signal and an extracted signal in order to enchance an operation reliability of the optical fiber element. CONSTITUTION: An optical fiber grate comprises a first optical fiber grate inclined to one side direction(x-direction) and a second optical fiber grate inclined to another side direction(y-direction) and overlapped with the first optical fiber grate. An optical fiber element comprises a first optical fiber wave guide(24) having a first and second optical fiber arranged in a horizontal direction and apart from each other, and having a signal input terminal(A) and a signal extracting terminal(B); a second optical fiber wave guide(26) having a symmetric structure to the first optical fiber wave guide and having a signal adding terminal(C) and a signal output terminal(D); and a mode converter(17) disposed between the first optical fiber wave guide and the second optical fiber wave guide, having the inclined optical fiber grate within a coupling region(18) where a first and a second optical fibers(21,23) are fusion-coupled, and for performing a mode conversion at a specific wavelength for signals input from the signal input terminal(A) and the signal adding terminal(C).
