Abstract (en)

[origin: WO2006062300A1] Provided is a highly efficient silicon-based light emitting diode (LED) including a Distributed Bragg Reflector (DBR), an n-type doping layer, and a p-type substrate structure. The silicon-based LED includes: a substrate having a p-type mesa substrate structure; an active layer that is formed on the substrate and has a first surface and a second surface opposite the first surface; a first reflective layer facing the first surface of the active layer; a second reflective layer that is located on either side of the p-type substrate structure and faces the second surface of the active layer; an n-type doping layer sandwiched between the active layer and the first reflective layer; a first electrode electrically connected to the n-type doping layer; and a second electrode electrically connected to the p-type substrate structure.
