Photonic Computing
We are now in the age of "big data". To handle such a vast amount of digital information, efforts in improving the performance of computing and storage is coming to an end because of physical limitations. Making use of photonics is a very promising approach to this end. However, we lack the understanding and fabrication know-how of this field because it is still at its relative infancy compared to traditional computing architectures. In 2015, our group has demonstrated, for the first time, a "non-volatile" memory cell using "light" and phase-change materials (PCMs) (click here for details). Keeping the record of storage bits per device and developing different controlling ways recently, we try our best to carry this area forward and pioneer "all-optical" and "neuromorphic" computing.
