The blazed grating optical fiber polarizing coupler comprises a first optical fiber with a Bragg diffraction grating formed in its core at substantially the Brewster's angle with respect to an optical axis of the first optical fiber, a second optical fiber, also with a Bragg diffraction grating formed in its core at substantially the Brewster's angle with respect to the optical axis of the second optical fiber. The Bragg diffraction grating of the first optical fiber is oriented substantially parallel to the Bragg diffraction grating of the second optical fiber so that the cladding of the first optical fiber and the cladding of the second optical fiber are interposed between the cores of the first and second fibers. An optical signal may be coupled from the first optical fiber into the second optical fiber and polarized in the process.
