✦ Synopsis

We have shown that the enhancement of carrier confinement by introducing a multiplequantum-barrier into the cladding region of semiconductor heterostructure lasers is substantially less than what was previously predicted, because the reflectivity of an electron incident on a multiple-quantum-barrier depends on its transverse momentum, thereby limiting the expected improvement in laser characteristics.
