Professor Juejun Hu’s research group focuses on novel materials and devices that exploit the interactions between light and matter. His work spans a wide spectrum of applications, including on-chip sensing and spectroscopy. By capitalizing on digital Fourier transform technology, Professor Hu and his group have created miniaturized and rugged sensors suitable for mass production, employed in industrial process control, medical imaging, and space applications. A significant aspect of their research involves optical phase change materials—materials whose optical properties can be modified by undergoing solid-state phase transitions. Utilizing these materials, the group has pioneered a series of cutting-edge reconfigurable optical devices that can be reprogrammed to adapt to specific tasks. Their applications extend to flexible photonics, polymer photonics, biomedical monitoring, high-speed data communications, optical imaging, sensing, and consumer automotive electronics. Moreover, their work includes developing chip-scale one-way valves for photons that could become integral to next-generation optical communication systems.
