For instance, areas like metamaterials and two-dimensional materials have caught the scientific community’s attention for their unique electromagnetic properties, which can be tailored at the nanoscale to manipulate infrared light with unprecedented precision.

The integration of these novel materials and concepts has not been accidental but rather a deliberate, forward-looking strategy at Professor Lu’s institution. By embracing the study of metamaterials, researchers have unlocked new pathways to engineer infrared waves that traditional materials cannot achieve, such as achieving negative refractive indices or topological robustness. Similarly, two-dimensional materials like graphene offer extraordinary electronic and optical characteristics, enabling highly sensitive and tunable infrared detectors and emitters. These advances are critical because they form the foundational building blocks from which next-generation infrared devices can be developed, spanning from quantum sensors to adaptive imaging systems.

In addition to materials science, theoretical frameworks such as non-Hermitian physics have been embedded into the research portfolio. Non-Hermitian physics explores systems that do not conserve energy in the traditional sense, often exhibiting exotic phenomena like exceptional points and parity-time symmetry. The application of these principles in infrared systems opens the door to designing devices with enhanced sensitivity and resilience. For example, sensors operating near exceptional points can exhibit drastic responses to minimal environmental changes, potentially revolutionizing the precision of infrared measurement tools.
