Light People | Prof. Wei Lu spoke about infrared physics.

Professor Wei Lu is a leading scientist in infrared physics. He proposed the paradigm of localized manipulation over electrons and photons for infrared detection, addressing the critical challenge of dark current suppression in long-wave infrared detectors. His direct observation of the Haldane gap in quasi-one-dimensional magnetic materials was one of the earliest experimental validations of the Haldane's conjecture - a crucial step in the theoretical discoveries of topological phases of matter that led to 2016 Nobel Prize in Physics for Duncan Haldane. Beyond fundamental research, Prof. Lu and his team developed a series of new advanced infrared detectors on multiple remote sensing satellite platforms. During his tenure as the Director of China's State Key Laboratory of Infrared Physics and President of the Shanghai Institute of Technical Physics (SITP) at the Chinese Academy of Sciences, he led the strategic development of the institutions, contributing to China's breakthroughs in spaceborne remote sensing technologies.
