报告摘要:
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.
硅由于自身材料性质限制了其在某些光学方面的应用,所以寻找新的更好的材料平台一直是一个很重要的研究方向。本报告将介绍欧海燕教授团队碳化硅基光电子器件方面的最新研究成果。主要介绍两种有代表性的器件: 发光器件和波导器件。对于发光器件,我们用重掺施主-受主对和制作多孔结构的方法分别实现了强的可见光。混合B-N共参的黄光和多孔结构的蓝绿光,我们实现了高显色指数的白光。对于波导器件,由于碳化硅的宽禁带,在通讯波长的双光子吸收比硅要低很多,其在非线性应用前景很广阔。本次报告也将分享这方面的最新成果。
