Sandi国家实验室的一组研究人员采用逐层周期结构法,并借助微电子加工技术。成功地在硅片上制备了三继红外电光子晶体。这种品体不但提供了一种约束和控制光的方法,并且能够在三维内将光定位在个立方波长的某一个点上的能力,使制作单模发光二极管成为可能。此外,三维光子晶体在戏外发射工作领域具有非常乐观的应用前景。 A group of researchers at Sandi’s National Laboratory used layer-by-layer periodic structure methods, using microelectronics processing techniques. Successfully prepared in the silicon triple-infrared photonic crystal. Not only does this body provide a method of restraining and controlling light, but also the ability to position the light at a single cubic wavelength in three dimensions makes it possible to fabricate single-mode LEDs. In addition, 3D photonic crystals have very promising applications in off-camera launches.
