Abstract
The DARWIN mission aims to detect weak infra-red emission lines from distant orbiting earth-like planets using nulling interferometry. This requires filtering of wavefront errors using single mode waveguides operating at a wavelength range of 6.5-20 μm. This article describes the optical design of the fibers, the manufacturing protocol, the packaging for operating at cryogenic environment and various optical characterisations performed. The latter includes investigation on the effect of gold and silver absorption coatings, anti-reflection coating, fiber length on higher order mode suppression and attenuation of the fibers.
