Since 2000, QSIP, Quantum Structure Infrared Photodetector, is the biennial international conference dedicated to infrared photodetection. The 2026 edition will be held in the South of France from June 14 to 19 and will address all aspects of IR detection: from the epitaxial growth of quantum structures to the electro-optical characterization of detector focal plane arrays, including modeling, design, transport properties and device processing. University laboratories, research institutes and companies of the domain will participate to present their latest work and to discuss about the newest scientific and technical advances in this highly competitive research field.
