One of the critical issues for nulling interferometry breadboards for exo-earth detection relies on the possibility to manufacture and properly characterize optical waveguides that present suitable single mode behaviors in the foreseen spectral range (4-20 μm). We developed a dedicated bench for the characterization of available guides for the considered spectral range, in particulary silver halide fibers. This interferometric bench achieves modal characterization in nulling mode and spectral transmission in Fourier Transform spectrometer mode, defining the single mode domain of the components. We present the experimental setup and its performances. We present also some characterization of their single-mode behavior according to the injection conditions. These measurements are very useful for the conception of optimized components.
