 技術摘要： |
一種發光元件，包括一發光單元，及一表面電漿耦合單元，與發光單元連結。發光單元包括一第一型半導體層、一位於第一型半導體層上之主動層，及一位於主動層上之第二型半導體層。在一實施例中，表面電漿耦合單元為一金屬層，且金屬層接觸第二型半導體層。在另一實施例中，金屬層和第二型半導體層之間設置有一介電層。
The invention provides a light-emitting device, comprising a light-emitting element and a surface plasmon coupling element connected to the light-emitting element. In an embodiment of the invention, the surface plasmon coupling element comprises a dielectric layer connected to the light-emitting element and a metal layer on the dielectric layer. In another embodiment of the invention, the light-emitting device is a light-emitting diode, comprising an active layer between an n-type semiconductor layer and a p-type semiconductor layer, and a surface plasmon coupling element adjacent to the n-type semiconductor layer. In a further embodiment of the invention, a current spreading layer on a second type semiconductor layer of the light-emitting device includes a plurality of strip-shaped structures, and the surface plasmon coupling element is disposed on the current spreading layer and filled into the gap between the strip-shaped structures of the current spreading layer.
