Title: Christopher Ertsgaard and His Photonics Patents.

Introduction

Christopher Ertsgaard is an inventor based in Broomfield, Colorado, whose patent work focuses on photonics and optical technologies. He is associated with Quantinuum LLC and is named on 2 patents.

Latest Patents

Ertsgaard’s listed patents address waveguide design and precision alignment for optical systems.

“Waveguide with Periodic Index of Refraction Cladding” describes a waveguide designed to reduce optical power loss. Its core is surrounded, at least in part, by layered cladding with a periodic refractive index. The core’s refractive index is greater than that of the adjacent cladding layer.

“High Precision Photonic Alignment Device” covers alignment devices and methods for making and using them. In one example, a substrate contains inputs, outputs, and waveguides that connect them. The input positions are determined using measured positions of optical fiber cores secured in coupling elements, while the outputs are arranged to deliver optical signals to target locations on a receiving device.
