Abstract
We report on the progress in developing cryogenic delay lines and integrated optics components. These are some of the critical components needed to enable far-infrared direct-detection interferometers. To achieve background-limited performance in the 40 to 400 μm region, the interferometer optics and delay lines must be cooled to near liquid Helium temperatures. Our cryogenic delay line designs incorporate a number of novel features and has been operated at liquid nitrogen temperatures. Our integrated optics effort has focused on producing single-mode spatial filters and beam combiners.
