报告题目：Novel Nanophotonic Devices: Harnessing Light–Matter Interaction at the Nanoscale
报告摘要：Nanophotonics studies light generation, detection, and manipulation at the nanoscale. Photonics as a field began with the invention of the laser in 1960, with other following developments including the laser diode in the 1970s, optical fiber for data transmission, and the erbium-doped fiber amplifier. These inventions formed the basis for the telecommunications revolution of the late 20th century and provided the infrastructure for the Internet. With the development of nanotechnology, photonics has now entered into the nano regime, covering a huge range of science and technology applications including computation and communication, biological and chemical sensing, medical diagnostics and therapy, and 3D display technology, etc. In this talk, I will introduce several novel nanophotonic devices recently investigated in my research group. By exploiting the light–matter interaction in an untraditional material or in an unconventionally designed nanostructure, those devices are shown to achieve new functionalities or exhibit exceptional performance enhancement compared with their traditional counterparts. They hold great promise for many burgeoning areas in science and engineering, such as single-molecule detection, laser cooling, and information processing.
