We show that two rows of photonic lattices on each side of a narrow diffraction-inhibited beam are sufficient for confinement, enabling the launching of multi-beams with an interval of one lattice constant for independent propagation. A few integrated photonic circuit building blocks including arbitrary angle bends, power splitter and intersection are designed to realize flexible controls of the diffraction-inhibited beams. In addition, under wide beam illumination, incident beam power is well separated by the lattices rows, facilitating the simultaneous excitation of multiple diffraction-inhibited beams. These novel effects and building blocks offer exceptional opportunities for multichannel photonic routing.
