■报告简介：Due to the inherent limitations of silicon in photonic application, new material platforms are always very interesting research
subjects. In this talk, our pioneered work on silicon carbide (SiC) based photonic devices will be presented, with focus on two representative devices: light emitters and waveguide components. We have demonstrated strong visible light emission by either doping SiC heavily by donor-acceptor pair (DAP) recombination or forming porous structures in SiC. By combining strong yellow emission from B-N co-doped SiC and the blue-green emission from porous SiC, a high color-rendering- index white light source is achieved. SiC optical waveguides outperform Si waveguides with respect to low two-photon absorption. Our recent results on SiC waveguides will be discussed as well.
