Title:
T203-19MM
FIR linear Detector Array
The purpose of this activity is to develop a novel detector technology to realize the linear focal plane array (FPA) for the
DARWIN mission spectrometer. The linear array must cover the wavelength band going at least from 6 to 18 µm with
state-of-the-art sensitivity and take into account the mission thermal budget. The wavelength band and sensitivity
requirements are essentially constrained by extra-solar planet contrast considerations. In addition, system design issues
favour higher operating temperatures than those offered by existing detector technologies. Phased contract.
Deliverables:
Technology demonstrator
Current TRL: TRL2 Target TRL: TRL3 Application Need/Date: TRL5 by 2010
Application/Mission: Darwin Contract Duration: 24 months
SW Clause : - Dossier0 Ref.: T-7990
Consistency with Harmonisation
Roadmap and Conclusions:

Title:
Single mode waveguide
The wavefront quality of the interfering beams has to be improved in order to achieve the required nulling performance. This
improvement can best be performed by filtering by means of propagating the wave in a single mode waveguide.
Pre-developments of IR single mode fibres have been successfully completed, resulting in the identification of promising
technologies such as SilverHalide, Calcogenide and Tellurium based waveguides. In this activity the manufacturing process
shall be refined and the detailed properties of the waveguides determined.
Deliverables:
Process assessment, technology demonstrator.
Current TRL: TRL2 Target TRL: TRL3-4 Application Need/Date: TRL5 by 2010
Application/Mission: Darwin Contract Duration: 24 months
SW Clause : - Dossier0 Ref.: T-7991
Consistency with Harmonisation
Roadmap and Conclusions:
The proposed activity is not directly related to a harmonised subject.
