Title: Semiconductor optical element
Inventor: UOMI KAZUHISA
IPC: H01S5/34
Filed: 1989-07-10
Abstract: PURPOSE:To realize a laser oscillation in a low threshold current and moreover, a high quantum effect in a quantum well type laser by a method wherein the side of a conduction band has an equivalent band end discontinuous energy value, which is formed of the lowest energy state of a miniband to be formed in a barrier layer by a superlattice structure and a well layer and is larger than that on the side of a valency band. CONSTITUTION:Minibands are formed in respect to electrons and holes in a superlattice structure. Energies of the minibands in the barrier of this superlattice structure are equivalent to the depths of wells to a quantum well layer, in short, become DELTAEc and DELTAEv. The energies DELTAE of the minibands are inversely proportional to the effective masses of the electrons and the holes. In an InGaAs(P) system, the effective mass of electrons is about 1/10 of that of holes. Accordingly, a DELTAEe of the miniband of electrons on the side of a conduction band, that is, the DELTAEc becomes about 10 times as large as a DELTAEh of the miniband of holes on the side of a valency band, that is, the DELTAEv. In such a way, a superlattice type quantum barrier is used in a system of DELTAEv>DELTAEc as well. Thereby, the relation of DELTAEc>DELTAEv can be made.
