Light emitting diode having light-emitting and light-absorbing regions |
摘要 |
An active layer of a light-emitting diode is surrounded jointly by a pair of clad layers and a pair of block layers. The active layer includes a light-emitting portion and a light-absorbing portion which are continuously formed in one body. The light-emitting portion emits light when carriers are injected thereinto between the pair of clad layers, and the light-absorbing portion absorbs light coming from the light-emitting portion. A bandgap of the light-absorbing portion may be smaller than that of the light-emitting portion.
