1
Photonics instrumentation for mid-IR
interferometric facilities

• Lucas Labadie
• Galaxy and Cosmology Group Retreat

2
Why we need high angular resolution ?
Imaging
SED
Visible, NIR
MIR
Sub-mm
3
Increase the dynamic range (an AO for the poor)
coupling
SM waveguide
Filtering
Instrumental atmospheric phase errors

• Incremental upgrade

• Flexibility

Beam combination

• Miniaturization

• Lower costs

And in the mid-infrared ?
