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.
