Title: Lewis R. Lowry: Innovator in Light-Activated Technology
Introduction
Lewis R. Lowry is a notable inventor based in Greensburg, PA (US). He holds a total of 3 patents that showcase his contributions to the field of light-activated technology. His innovative work has significantly impacted the development of silicon switches and thyristors.
Latest Patents
One of his latest patents is the "Light Activated Silicon Switch with Etched Channel in Cathode Base." This invention involves a light-activated silicon switch (LASS) that transmits light from a trigger source to target areas prepared in the cathode-base and anode-emitter regions of the silicon wafer. The target areas are V-shaped channels etched into the silicon wafer. Light transmitting conduits, consisting of a central core of light transmissive material with an outer cladding, are arranged to transmit light energy to the respective target areas. The cladding is removed at one end of each conduit for optically coupling the light to the proximate target area, while the other end is designed to receive a light trigger signal of the appropriate wavelength.
Another significant patent is the "Package for Light-Triggered Thyristor." This invention describes a hermetically sealed package for a light-triggered thyristor, which is mounted within the cavity of an insulating body. Cathode and anode pole pieces are mounted on opposite sides and electrically coupled with the thyristor. Annular flanges are provided to form hermetical seals between the body and pole pieces. A light pipe is mounted in a radially extending slot formed through a face of one pole piece, optically coupling the light-sensitive region of the thyristor with a triggering light source.
