Title: Matthew D. Cole and Optical Wavelength Control

Introduction

Matthew D. Cole is an inventor associated with South Boston, Massachusetts, and Lightmatter, Inc. His patent work addresses a challenge in optical communications: keeping laser emission wavelengths aligned with the channel grid used in wavelength division multiplexing (WDM) systems.

Latest Patents

Cole is associated with 1 patent, titled “Laser System with Active Wavelength Control.” The invention describes an optical source connected to a feedback loop that monitors whether its emission wavelengths match designated WDM channels. The system adjusts the source’s operating parameters to maintain alignment despite temperature fluctuations.

The approach combines coarse and fine spectral alignment and uses two thermoelectric coolers. One cooler is thermally coupled to the laser chip, while the other is coupled to a multiplexer chip that monitors the emission wavelengths against the WDM grid.

Career Highlights

Cole’s patent reflects work on stabilizing optical sources for wavelength-division-multiplexing applications. By combining feedback-based adjustments with thermal control, the described system aims to maintain reliable wavelength alignment as operating temperatures change.

Collaborations

Cole’s listed coworkers include Srinivasan Ashwyn Srinivasan and Jessie Rosenberg. The patent’s described system brings together a laser chip, a multiplexer chip, and temperature-control components to support spectral alignment.

Conclusion

Matthew D. Cole’s patent work focuses on active wavelength control, combining feedback and thermal management to help optical sources remain aligned with WDM channel grids.
