Abstract
An injection laser is provided with quantum size effect transparent waveguiding. The laser includes an active layer having an active region wherein carrier recombination occurs under lasing conditions. The active layer has passive waveguide end regions between the active region and the laser end facets that are sufficiently thin in layer thickness to form a transparent waveguide having a quantum well effect so that radiative recombination will not occur in these regions.
