The low cost, ultra high speed, large capacity and long distance fiber transmission have been the targets of people's pursuit with the explosive growth of information demand. In addition, every milestone in optical communications relies on breakthroughs in basic optoelectronic devices. At present, one of the trends in optical communications is that, like the electrical integrated circuits and o...

Extensive efforts have been made to explore high-power vacuum electronic devices and super-resolution electromagnetic imaging technologies. Vacuum electronic devices use free-space electrons to excite electromagnetic-wave radiation between microwave to terahertz band, and play key roles in satellite, radar, wireless communication, and a series of other applications. High efficiency, high reliab...

Carbon Based Electronics: Carbon nanotube based electronic devices, photoelectronic devices and system integrationExtensive efforts have been made to explore alternative channel materials to push the Moore’s Law forward. Carbon nanotubes (CNTs), as an ultrathin and one-dimensional semiconductor material, have ultra-high carrier mobility (for both electrons and holes), large saturation speed, l...
