Title: Alain Mugnier and His Patent for a Tunable Laser

Introduction

Alain Mugnier is an inventor associated with Penvenan, France, and Exfo Optics SAS. His recorded patent work includes 1 patent concerning tunable laser technology.

Latest Patents

Mugnier’s patent, “Tunable Laser Having Low Intra-Cavity Chromatic Aberrations,” describes a tunable external-cavity laser and a laser source based on that design. The laser uses two reflective surfaces to form a cavity, an active waveguide to amplify light, and a wavelength-selective filter to choose the emission wavelength within a tuning range.

The design also uses an imaging lens and a collimating lens system to direct the optical beam. The imaging lens introduces positive chromatic aberration, while a complex collimating lens introduces negative chromatic aberration to at least partially compensate for it. This approach is intended to reduce intra-cavity chromatic aberrations as the laser’s wavelength is tuned.
