Józef Piotrowski

End users can look forward to a variety of benefits from current research, including high-performance and fast-response single-element devices. Within the next year or so, end users can expect significant performance improvements in medium-wavelength IR (3 to 5 μm) and long-wavelength IR (8 to14 μm) photodetectors operating without cryogenic cooling. These high-temperature devices will gain from the use of more advanced architectures, the integration of micro-optics and active elements, and the use of photonic crystals. The HgCdTe and related Hg-based alloys will remain the design...Read full article
