Abstract
A theory of coherent lasing on a double-well structure with asymmetric barriers is constructed. On account of the appearance of a termination point of the bottom subband, such a structural element permits strong suppression of intersubband relaxation involving the emission of an optical phonon. It is shown that such a laser possesses low threshold currents and high lasing power, and it can operate without a population inversion.
