This document is a recap of an oral presentation made at Nice during
the INSU Astrophysics Detector Workshop 2008. It aims at giving an
overview of the achievements and ongoing developments presently carried
out at CEA-LETI in the field of Infrared focal plane array. Although
most of the research actually performed at LETI is not driven by space
oriented application, the excellence and the cutting edge of the outcome
is or can be applied to space-dedicated components. This paper focus
on features and developments from which astrophysics observation would
benefit in the near future on the European market. This encompassed
“traditionnal” developments such as format enlargement, low dark current
technology such as p/n structure but it also shade light on promising
and thrilling development such as avalanche photodiode array. It eventually
gives some hints of none MCT technologies processed at LETI.
