Our group is a NanoOptoelectronic Research Group in the Department of Physics at Fudan University. Our work covers a broad range of physics, devices, and instrumentation of small electronic and optical systems. Basically we are utilizing modern advanced nanofabrication techniques to explore innovative and functional optoelectronic devices. Meanwhile, we are particularly interested in physics of the light-matter interaction in hybrid systems which comprise of low-dimensional electron systems and subwavelength optical or plasmonic cavities. Such systems often exhibit exotic electronic and/or optical behaviors which can lead to the invention of unconventional optoelectronic devices. In addition, we actively develop new experimental systems based on our own invented devices and hopefully expand the research tools and capabilities of our humankind in various areas such as physics, nanoelectronics, chemistry and biology.
