  • Optical coupler
    Patent number: 9158175
    Abstract: In some embodiments, an optical coupler comprises a substrate, and first and second optical waveguides positioned on the substrate. The second optical waveguide extends adjacent to and parallel with the first optical waveguide for at least one effective coupling length, the at least one length having a first end and a second end. The coupler further comprises a first phase shift section forming a portion of the first optical waveguide and located at a first predetermined distance from the first end of the length, and a second phase shift section forming a portion of the second optical waveguide and located at a second predetermined distance from the second end of the length, wherein the first predetermined distance is approximately equal to the second predetermined distance, and wherein the second optical waveguide does not have a phase shift section located at the first predetermined distance from the first end of the length.
