SYSTEMS AND METHOD FOR ROUTING OPTICAL SIGNALS

摘要

Systems and a method for routing optical signals are disclosed. One system includes a first large core hollow metal waveguide (505) configured to guide a substantially coherent optical beam (506). A second large core hollow waveguide (507) is optically coupled to the first waveguide (505) with a coupling device (510). The coupling device is configured to divide the coherent optical beam into a transmitted beam (512) and a reflected beam (514). Beam walk-off within the coupling device (510) causes the transmitted beam (512) to be shifted by an offset amount (518). The second large core hollow metal waveguide (507) is shifted from the first large core hollow metal waveguide (505) by approximately the offset amount (518) to receive the shifted transmitted beam (512).
