    • A silicon-based light emitting diode simultaneously adopts doping layers and Distributed Bragg Reflector (DBR). The silicon-based light emitting diode includes an active layer having mutually opposing a first side and a second side. A first reflecting portion faces with the first side of the active layer, and a second reflecting portion faces with the second side of the active layer. A first doping layer is interposed between the active layer and the first reflecting portion. A second doping layer is interposed between the active layer and the second reflecting portion. A first electrode is electrically connectable to the first doping layer, and a second electrode is electrically connectable to the second doping layer. Here, At least one of the first reflecting portion and the second reflecting portion has the DBR that is formed by alternately stacking two kinds of differently composed silicon-containing insulating layers and a gate.
    • 硅基发光二极管同时采用掺杂层和分布式布拉格反射器(DBR)。 硅基发光二极管包括具有相对于第一侧和第二侧的有源层。 第一反射部分面向有源层的第一侧,并且第二反射部分面向有源层的第二侧。 第一掺杂层介于有源层和第一反射部分之间。 第二掺杂层介于有源层和第二反射部分之间。 第一电极可电连接到第一掺杂层,第二电极可电连接到第二掺杂层。 这里,第一反射部和第二反射部中的至少一个具有通过交替堆叠两种不同构成的含硅绝缘层和栅极而形成的DBR。
