Title: Jacques P. Govignon: Optical Wavelength Stabilization

Introduction

Jacques P. Govignon is an inventor associated with Watertown, Massachusetts, and The Charles Stark Draper Laboratory, Inc. His patent work addresses the stabilization of broadband optical sources, helping maintain a consistent center wavelength despite environmental changes and component aging.

Latest Patents

Govignon is credited with 1 patent, titled “Method and Apparatus for Stabilizing a Broadband Source.” The invention uses an optical power divider to create two signals from both a broadband source and a reference wavelength source. It compares the power ratios of the signal pairs and uses their difference to adjust the broadband source’s wavelength. Because environmental conditions and component aging affect both sets of ratios similarly, the comparison helps stabilize the broadband source’s center wavelength against the reference.

Career Highlights

Govignon’s patent reflects work on optical measurement and control systems. The disclosed method is designed to compensate for factors such as temperature and incident radiation that can affect optical components and wavelength stability.

Collaborations

The patent record identifies William P. Kelleher and Reinhardt Leon Willig as Govignon’s coworkers. His professional association with The Charles Stark Draper Laboratory, Inc., places this invention within the laboratory’s broader research and engineering environment.

Conclusion

Jacques P. Govignon’s patented method offers a way to stabilize a broadband optical source by comparing its signals with those of a reference source. The invention highlights the role of comparative optical measurements in maintaining wavelength consistency under changing conditions.
