IPC: H01S5/343
Filed: 1992-04-14
Abstract: PURPOSE:To make the oscillation wavelength short without increasing the oscillation current threshold value, by using (AlxGa1-x)1-yInyP having a lattice constant smaller than that of a GaAs substrate as the barrier layer of the active layer of a quantum well structure to enhance the energy barrier of the barrier layer. CONSTITUTION:On one principal surface of a GaAs substrate 1, a semiconductor laser is provided which includes an active layer 5 of a quantum well structure consisting of a (Al2Ga1-z)1-lInlP quantum well layer 5a and a (AlxGa1-x)1-yInyP barrier layer 5b having a lattice constant smaller than that of the GaAs substrate. In addition, the one principal surface of the GaAs substrate is a plane slanting by 5 to 15 deg. from the {l00}-face to the <011>-direction. Accordingly, electrons confined in the well layer are prevented from being emitted by the tunnel effect or heat and the quantum energy level of the conduction band relatively shifts to the high energy side, so that the oscillation wavelength can be made short without increasing the oscillation current threshold value.
