Title: Eric A Armour: Innovator in Semiconductor Laser Technology
Introduction
Eric A Armour is a prominent inventor based in Albuquerque, NM (US). He has made significant contributions to the field of semiconductor laser technology, holding a total of 2 patents. His work has advanced the understanding and application of laser diodes, particularly in high optical power output.
Latest Patents
One of his latest patents is for an "Unstable Resonator Semiconductor Laser." This invention describes a semiconductor laser diode that provides high optical power output in a single diffraction-limited farfield lobe. It utilizes a conventional Fabry-Perot resonant cavity and a planar well graded index separate confinement heterostructure (QW-GRINSCH) active region. The design includes an antiguide region that is optically coupled to the active region of the laser, featuring a lateral variation in the effective index of refraction. This variation forms a diverging medium that increases losses for higher order optical modes within the resonant cavity. The waveguide medium's thickness varies in a parabolic function laterally, and the antiguide region is enclosed by GaAs layers to minimize oxidation during device fabrication.
Another notable patent is for a "Radial Epitaxial Reactor for Multiple Wafer Growth." This invention presents an improved gas distribution scheme for a multi-wafer radially injected convergent horizontal epitaxial reactor. It includes two outer distribution rings, an outer injection ring, an annular susceptor, and a central exhaust tube. The design compensates for the depletion of reactant gases along the substrate by converging the gas stream from the outer injection ring into the central exhaust tube. The injector ring features numerous evenly spaced diffuser orifices that allow for laminar flow patterns in the growth chamber. This compact design also allows for water cooling of the quartz during deposition and includes a resistive bakeout furnace for etching and cleaning the reaction chamber.
