Systems and a method for routing optical signals are disclosed. One system includes a first large core hollow metal waveguide configured to guide a substantially coherent optical beam. A second large core hollow waveguide is optically coupled to the first waveguide with a coupling device. The coupling device is configured to divide the coherent optical beam into a transmitted beam and a reflected beam. Beam walk-off within the coupling device causes the transmitted beam to be shifted by an offset amount. The second large core hollow metal waveguide is shifted from the first large core hollow metal waveguide by approximately the offset amount to receive the shifted transmitted beam.
