Transmission behaviors of single mode hollow metallic waveguides dedicated to mid-infrared nulling interferometry
Laetitia Abel-Tiberini, Lucas Labadie, Brahim Arezki +4
This paper reports the characterization of hollow metallic waveguides (HMW) to be used as single-mode wavefront filters for nulling interferometry in the 6-20 microns range. The me…
Technology challenges for space interferometry: the option of mid-infrared integrated optics
L. Labadie, P. Kern, P. Labeye +5
Nulling interferometry is a technique providing high angular resolution which is the core of the space missions Darwin and the Terrestrail Planet Finder. The first objective is to…
Transmission measurement at 10.6 microns of Te2As3Se5 rib-waveguides on As2S3 substrate
C. Vigreux-Bercovici, E. Bonhomme, A. Pradel +3
The feasibility of chalcogenide rib waveguides working at lambda = 10.6 microns has been demonstrated. The waveguides comprised a several microns thick Te2As3Se5 film deposited by…
Mid-infrared laser light nulling experiment using single-mode conductive waveguides
L. Labadie, E. Le Coarer, R. Maurand +4
Aims: In the context of space interferometry missions devoted to the search of exo-Earths, this paper investigates the capabilities of new single mode conductive waveguides at prov…
M-lines characterization of selenide and telluride waveguides for mid-infrared interferometry
Lucas Labadie, Caroline Vigreux-Bercovici, Annie Pradel +3
Nulling interferometry is an astronomical technique that combines equal wavefronts to achieve a deep rejection ratio of an on-axis star, and that could permit to detect Earth-like…
Modal Filtering for Nulling Interferometry-First Single-Mode Conductive Waveguides in the Mid-Infrared
L. Labadie, P. Labeye, P. Kern +3
This paper presents the work achieved for the manufacturing and characterization of first single-mode waveguides to be used as modal filters for nulling interferometry in the mid-i…
