Integrated Optics (IO) beam combiners implemented in waveguide are a compact, low-mass alternative to beam combiners designed using quasi-optical techniques. Here we present modeling (performed in CST Microwave Studio at 30 THz) and experimental results (done at X-Band) for IO beam combiners based on "magic-T" waveguide structures. A magic-T can be configured either for beam combining or nulling. This work was originally done in support of the Terrestrial Planet Finder (TPF) project, and has a wide variety of potential interferometric applications.
