Introduction

David N Pulsifer is an accomplished inventor based in San Mateo, California. He holds a total of five patents, showcasing his expertise in the field of optical glass technology. His innovative contributions have significantly advanced the development of fiber and lens preform structures.

Latest Patents

Among his latest patents is a fiber and lens preform with a deep radial gradient layer. This invention involves a fiber preform structure made of optical glass, featuring a central core of a first material and a surrounding tube of a second material. A deeply placed bonded layer is integrally formed between the core and tube through a heat-driven interdiffusion process. This interface layer exhibits material characteristics that are related to the interdiffused properties of the rod and tube materials. The interdiffusion process is performed while supporting the combined rod and tube structure, and the preform is rotated during heating to maintain geometric symmetry. An encapsulating carrier supports the preform in all dimensions during the heating process. Another notable patent is a glass preform with a similar deep radial gradient layer, constructed with the same principles and methods.
