Abstract

LYNRED is oriented towards excellence in II-VI, III-V and bolometers technologies, covering all Society’s needs in term of infrared detection. Our vision is to preserve and protect, and more than ever, our goal is to provide the right technology to the field missions, spatial and industrial applications, and more generally the right technology to customers’ needs. For this purpose we are developing for the next generation pitch, MCT HOT technology, for extended MW band as well as III-V HOT MW blue band technology. Many challenges have to be addressed for future small pitch, large format and HOT detectors. Electrical and optical crosstalks as well as image quality and stability, are one of the prime concern for detectors with pixel pitch below 10μm. We will discuss about the trade-off between the different material properties and detector performances to ensure mandatory minimization of Minimum Resolvable Temperature Difference (MRTD) for range optimization. We will then review latest 7.5μm pitch development at LYNRED, with SXGA formats, based on II-VI and III-V HOT materials, in terms of operability, residual fixed pattern noise (RFPN) and Modulation Transfer Function (MTF) optimizations.
