Abstract: 1,258,360. Luminescent materials and uses thereof. STANDARD TELEPHONES & CABLES Ltd. 25 Sept., 1970, No. 45732/70. Heading C4S. [Also in Division H1] A heterostructure injection laser, Fig. 5, comprises a GraAs p-n junction and a p-type GaAlAs heterostructure layer, and is formed with two adjacent and parallel V-shaped grooves which penetrate through the n-type GaAs and the junction into the p-type GaApAs, the structure having opposed electrodes 50, 52, with the electrode 50 restricted to a ridge 32 of n-type GaAs defined by the grooves so as to confine the injection current to the immediately adjacent portion of the p-n junction. An optical resonator is formed by cleaving the semi-conductor structure orthogonal to the grooves, while the parallel grooves are formed in a V-shape to suppress the generation of transverse radiation. A plurality of lasers are formed 'simultaneously by epitaxially growing a layer of zinc-doped p-type GaAlAs on one major surface of an n-type GaAs substrate, diffusion of the zinc into the substrate forming the p-n junction. The substrate thickness is then reduced by polishing to leave an n-type GaAs layer about 3 microns thick. Spaced pairs of grooves 30, Fig. 3, are formed in the structure by etching and the use of a photoresist, followed by the deposition of an insulating layer of SiO 2 . Windows are then etched through the insulating layer over the length of the ridges 32 and the electrodes deposited by flash evaporation. The structure is finally cleaved into individual laser chips. The electrode 50 is graded from a goldgermanium alloy through nickel to gold, while electrode 52 is graded from a gold-zinc alloy through nickel to gold.
