Optic Communication Program
In the 21st century, our daily life is characterized by an intensive information and data exchange. The technology of radio-over-fiber communication offers a platform to meet the demand of broadband information exchange (see the left diagram for the concept). The optic communication group focuses on the development of access networking technology. Our recent achievements include a long-reach (over 100km) low-cost passive optical network (PON) and a world-record >60GHz high-fidelity RoF technology. To meet the ever-increasing demand of mobile communication, our future research direction is to extend the RoF technology into tera-hertz data rate by leveraging the expertise of our tera-hertz research in the fundamental research group.
3D Holographic Data Storage and Display Technology
The omnipresent information flow demands high-density data storage and high-quality 3D image display. Our group’s research results had been honored with SID best paper award a few times. Our research achievements include a world-leading polymer-based holographic data storage technology (see the left diagram for the prototype), revealing a data storage capacity >420GB/disk and access speed >117Mb/sec, and a low power consumption eco-display technology with “Stencil-Field Sequential Color TFT LCD”. The SFSC TFT LCD technology is based on a series of patent-pending techniques, including fast response optical compensated bending LC device, RGB LED backlight arrays module, human visual model, novel image driving algorithm and high-efficiency OLED, etc. These techniques can also form the base for the future 3D display, which can support high- quality 3D image in a flat panel.
