Achieving high levels of contrast over broad bandwidths with segmented aperture telescopes is a key requirement to maximize the scientific yield for future exoplanet imaging missions and ground-based extremely large telescopes. The High-Contrast Spectroscopy Testbed for Segmented Telescopes (HCST) in the Exoplanet Technology Laboratory (ET Lab) at Caltech is designed to proof test new technologies aimed at tackling some of the most pressing and challenging goals of exoplanet science, namely the

Here we report on the status of a key milestone: Demonstration of 20% bandwidth nulling experiments using single mode fibers wavefront control.
