Title: Barrie Peter Keyworth: Innovator in Optical Components
Introduction
Barrie Peter Keyworth is a notable inventor based in Edmonton, Canada. He has made significant contributions to the field of optical components, holding a total of 2 patents. His innovative methods and apparatuses have advanced the technology used in creating optical elements.
Latest Patents
Keyworth's latest patents include a method and apparatus for making optical components by direct dispensing. This invention involves forming an optical element on the surface of a substrate by ejecting a curable light guide forming liquid from a nozzle onto the substrate and curing the liquid. A waveguide can be formed by moving the nozzle in a linear pattern over the substrate during the ejection process. The curing of the liquid may involve exposing it to ultraviolet radiation, which can be applied to only a small portion of the liquid. Furthermore, a multilayered waveguide can be created by ejecting an additional light guide forming liquid onto the first layer and curing it. The invention also describes the simultaneous formation of core and cladding by ejecting core forming liquid from an inner tube and cladding forming liquid from an annulus surrounding the inner tube. The apparatus for forming a light guide includes an xy movable support for the substrate, a nozzle that is movable in relation to the substrate, and a dispenser to regulate the dispensing of liquid. Liquid curing radiation is provided through a source of UV light, and a microlens can be formed by holding the nozzle stationary during dispensing.
