Abstract:
A semiconductor light emitting device, comprising:an n-type substrate; a double hetero junction structure formed on the n-type substrate, the double hetero junction structure at least including a Si-doped n-type cladding layer, an active layer, and a Zn-doped p-type first cladding layer; and a current blocking structure formed on the double hetero junction structure, the current blocking structure at least including an n-type current blocking layer and a second p-type cladding layer, wherein the n-type current blocking layer includes: a Se-doped n-type first current blocking layer adjacent to the Zn-doped p-type first cladding layer; and a Si-doped n-type second current blocking layer formed on the n-type first current blocking layer.
