Faster and Smaller: Enabling Future Photonics
The current opto-electronics industry is challenged by the requirements of miniaturized devices with faster response time for applications in information processing, transmission, and storage. What’s needed is the development of an optical nanotechnology that operates at a time scale of femtosecond (one millionth of a billionth of a second) and a length scale of a nanometer (one-billionth of a metre).
Dr. Qiying Chen is working on just that kind of development. As a Canada Research Chair in Photonics, Dr. Chen investigates new photonic materials and devices that can achieve temporal and spatial resolution in femtosecond and nanometer scales, respectively.
Prior to his appointment, Dr. Chen gained extensive experience in developing photonic materials and devices. For example, he created new types of optical recording devices and developed ultra-high density optical data storage at the nanometer scale (a huge increase in the storage density over current DVD technology). His breakthrough in ultrafast optical nonlinearity of nano-composite materials shows great promise for all-optical signal processing and switching in future generations of computing and communication networks.
In his present research, Dr. Chen is taking advantage of state-of-the-art ultrafast laser technology and scanning probe microscopes to study the physics and engineering of near-field optics, ultrafast optical spectroscopies, ultrafast photonic materials and light-wave circuits, and biophotonics. He and his team expect their research to reveal new principles, discover enabling technologies, and realize numerous applications for information technology, telecommunication, manufacturing technology, oceanography, and medicine and the life sciences.
