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: ONE OR MORE EPITAXIAL LAYERS OF A SEMICONDUCTIVE MATERIAL ARE DEPOSITED ON A SUBSTRATE IN A FURNACE BOAT CONTAINING FOR EACH LAYER TO BE DEPOSITED A RESERVOIR WELL ADJACENT TO BUT VERTICALLY ABOVE A GROWING WELL. A CHARGE OF THE INGREDIENTS OF EACH OF THE EPITAXIAL LAYERS IS PLACED IN A SEPARATE ONE OF THE RESERVOIR WELLS AND THE BOAT IS HEATED TO MELT THE CHARGES. THE MELTED CHARGES ARE SUCCESSIVELY POURED FROM THEIR RESPECTIVE RESERVOIR WELLS INTO THEIR ADJACENT GROWING WELLS AND THE SUBSTRATE IS PLACED INTO THE RESPECTIVE GROWING WELLS TO PERMIT AN EPITAXIAL LAYER TO DEPOSIT ON THE SUBSTRATE.
