(a) Relative phases of the |VV〉 with respect to the |HH〉 of the generated entangled state from different waveguides. (b) Fidelity of the generated states from several waveguides to the Bell states |Ф±〉 = |HH〉 ± |VV〉, displaying a possibility of directly and tunably generating Bell states with the proposed scheme and without any post-generation compensation steps.
