Title: Semiconductor laser element
Inventor: ENDO KENJI
IPC: H01S5/00
Filed: 1985-12-23
Abstract: PURPOSE:To enhance oscillating characteristics and reliability, by sequentially using Sn and Te from a layer, which is in contact with an active layer, as impurities, which are added to n-type semiconductor layers, and reducing the temperature dependence of an oscillating threshold voltage. CONSTITUTION:In this element, n-type semiconductor layers are formed by two or more layers, e.g., an n-type AlGaAS buffer layer 4 and an n-type AlGaAs second clad layer 3. The thickness of the semiconductor layer, in which Sn is added, i.e., the buffer layer, is formed less than 1/10 the diffusing length of holes. The carrier concentration of the semiconductor layer, in which Te is added, i.e., the clad layer 3, is made to be more than 10<17>cm<-3>. Then the injected carrier flows out to the buffer layer 4, and a leaking current is generated. Since the thickness of the buffer layer 4 is as thin as 1/10 the diffusing length of the hole, the value of the leaking current is sufficiently smaller than that of the current, which is consumed in an active layer 5. Thus, the temperature dependence of the oscillation threshold value becomes small, and both the excellent oscillation threshold value and high reliability can be provided.

IPC: H02K13/00
Filed: 1990-10-29
Abstract: PURPOSE:To remove the dispersion of contact pressure so as to get stable contact by inclining the face of the top part, which includes the part in contact with, at least, a commutator of a branch part, to the base material face of a plate-shaped metallic brush.
