Our group is dedicated to multidisciplinary fields including nano-optics, photonic/acoustic metamaterials, as well as life sciences. We aim to study the fundamental physics of nano-optics and its application in super-resolution imaging,  high-speed/low-cost optical modulation device, high sensitivity biology sensor, etc. High-throughput micro/nano-fabrication techniques are developed to manufactore novel 2D/3D structures.  We are the pioneer of acoustic metamaterial study to demonstrate the negative index and super-resolution focusing in ultrasonic wave.
