    摘要: In an edge emitting laser having a window region with a ridge-waveguide structure, particularly, in a short cavity type of a laser operated with a low current, there has been a problem of its operating current being increased due to current leakage of the window portion. To solve this problem, in the window region, between an n-type substrate and a p-type cladding layer, a semi-insulating semiconductor layer into which Ru is doped is inserted. Alternatively, a stacked structure of a Ru-doped layer and a Fe-doped layer is introduced.

    摘要: A light receiving element having excellent characteristics, including high sensitivity and high response speed, can be achieved by a light element comprising unit structures each having two pn junction semiconductor layers, and a lightly doped semiconductor layer having low impurity density, lower than those of the p-type regions and the n-type regions of the two pn junction semiconductor layers, and which is sandwiched between the two pn junction semiconductor layers. The p-type regions of the pn junction semiconductor layers are disposed opposite to each other on opposite sides of the lightly doped semiconductor layer, respectively, and the n-type regions of the pn junction semiconductor layers are disposed opposite to each other on the opposite sides of the lightly doped semiconductor layer, respectively. In a method of fabricating such a light receiving element, using controlled shutters or an ion beam apparatus, the layers are formed of optimum semiconductors, in an optimum thickness and in optimum impurity densities. In this structure, photogenerated carriers move mainly through the lightly doped semiconductor layer. Therefore, the lifetime of the carriers is increased, and the drift mobility of the carriers is enhanced, so that the light receiving element is able to function with a high sensitivity at a high response speed.

    摘要: For a semiconductor light emitting device using GaInNAs as an active layer, since GaInNAs includes N, the critical thickness is reduced and it is difficult to lengthen the wavelength of a laser beam. A semiconductor light emitting device is prepared, which has an active layer comprising a quantum well layer formed by successively stacking a GaInNAs layer and a GaInAs layer and GaAs barrier layers stacked on both sides of the quantum well layer. The quantum level of the conduction band is present above the conduction band edge of the GaInAs layer.

    摘要: High performance and high reliability of a semiconductor laser device having a buried-hetero structure are achieved. The semiconductor laser device having a buried-hetero structure is manufactured by burying both sides of a mesa structure by a Ru-doped InGaP wide-gap layer and subsequently by a Ru-doped InGaP graded layer whose composition is graded from InGaP to InP, and then, by a Ru-doped InP layer. By providing the Ru-doped InGaP graded layer between the Ru-doped InGaP wide-gap layer and the Ru-doped InP layer, the Ru-doped InGaP wide-gap layer and the Ru-doped InP layer not lattice-matching with each other can be formed as a buried layer with excellent crystallinity.

    摘要: Since the semiconductor devices including a stacked structure of group-III-V alloy semiconductor layers different in the kind of group-V constituent atom form the so-called band line-up of type II, band discontinuity in the heterostructure has impeded smooth transport of carriers and deteriorated device characteristics.According to the present invention, an energy band structure that makes it possible, in one energy band (e.g., a valence band), to smoothly transport carriers of one of two kinds (e.g., holes) by connecting energy discontinuity in an inclined form or stepwise, and at the same, in the other energy band (e.g., a conduction band), to maintain a barrier effect for carriers of the other kind (e.g., electrons) by retaining energy discontinuity, can be realized for improved transport characteristics of carriers at the heterointerface forming the band line-up of type II.
