| Zusammenfassung: | Intersecting quantum wells form a T-shaped structure. Quantum bound states exist due to the spreading out of the wave function in the T-junction region. The confined state leads to formation of a quantum wire in which one-dimensional carrier behavior extends along a wire-like region defined by the intersecting planes of the two wells. By embedding such a region in a T-shaped optical waveguide, a quantum wire laser characterized by low-threshold stimulated emission in the one-dimensional quantum limit is provided. |
