    Abstract: A diode laser is improved in order to produce an output in a single longitudinal mode. The laser has a rectangular body with two regions of differing conductivity type material. Extending from one surface of the rectangular body and into one of the regions of differing conductivity material is a third region. Although the third region is composed of the same general conductivity type material as the region into which it extends, it is more highly doped with conductivity modifiers (more conductive). This third region extends along one surface between the ends of the body and is spaced from the sides of the body. An electrical contact stripe is positioned on the one surface so that a portion of its width overlaps a portion of the width of the third region.

    Abstract: In depositing on a substrate by liquid phase epitaxy an epitaxial layer of a semiconductor material having a volatile element, an initial epitaxial layer of the semiconductor material of the substrate is first grown by liquid phase epitaxy on the substrate to provide a smooth, undamaged surface which is not contaminated with the volatile element of the semiconductor material to be deposited. Immediately upon removal of the substrate from the solution from which the initial epitaxial layer is deposited, the substrate is placed in the solution from which the desired epitaxial layer is deposited. Thus, the desired epitaxial layer is deposited on a smooth, undamaged surface which is not contaminated with the volatile element of the semiconductor material.

    Abstract: AN EPITAXIAL SEMICONDUCTIVE LAYER A SMOOTH SURFACE IS FORMED ON A SUBSTRATE BY FIRST DEPOSITING THE EPITAXIAL LAYER ON THE SUBSTRATE FROM A FIRST SOLUTION OF THE SEMICONDUCTIVE MATERIAL DISSOLVED IN A MOLTEN METAL SOLVENT AND THEN BRINGING THE EPITAXIAL LAYER HAVING A FILM OF THE FIRST SOLUTION THEREON INTO CONTACT WITH A SECOND SOULTION OF A MOLTEN METAL SOLVENT SATURATED WITH A SEMICONDUCTIVE MATERIAL AND CONTAINING A METAL WHICH INCREASES THE SURFACE COHESION OF THE SOLUTION. THE EPITAXIAL LAYER IS HEALD IN CONTACT WITH THE SECON SOLUTION ONLY LONG ENOUGH TO DISSOLVE THE FILM OF THE FIRST SOLUTION IN THE SECOND SOLUTION. THE SUBSTRATE IS THEN REMOVED FROM THE SECOND SOLUTION WITHOUT RETAINING ANY OF THE SECOND SOLUTION ON THE SURFACE OF THE EPITAXIAL ALYER SO S TO PROVIDE THE EPITAXIAL LAYER WITH A SMOOTH SURFACE.

    Abstract: Two layers of a semiconductor material composed of three or more elements are deposited in succession by liquid phase epitaxy on a substrate. The layers may be of different conductivity types to form a PN junction therebetween. The layers are deposited from separate solutions containing the semiconductor material and a suitable dopant. During the deposition of the first layer from one of the solutions, both of the solutions are treated in the same manner so that the composition of the second layer is the same as that of the first layer at the junction between the layers.
