Abstract:
1. A fiber polarizing coupler comprising: a first optical fiber comprising a first cladding, a first core, and a first optical axis, the first core having a first Bragg diffraction grating formed at substantially the Brewster angle with respect to the first optical axis, wherein the first Bragg diffraction grating has a period of approximately (λ a second optical fiber, comprising a second cladding, a second core, and a second optical axis, the second core having a second Bragg diffraction grating formed at substantially the Brewster angle with respect to the second optical axis; wherein the first Bragg diffraction grating is oriented substantially parallel to the second Bragg diffraction grating such that the first optical fiber is optically coupled to the second optical fiber; and the first cladding and the second cladding are interposed between the first and second cores.
