Title: Stéphane Schilt: Innovator in Dual-Comb Spectroscopy

Introduction

Stéphane Schilt is a prominent inventor based in Neuchâtel, Switzerland. He has made significant contributions to the field of spectroscopy, particularly through his innovative work on dual-comb spectrometers. With a total of 3 patents to his name, Schilt continues to push the boundaries of optical technology.

Latest Patents

One of Schilt's latest patents involves a dual-comb spectrometer that utilizes two lasers to output respective frequency combs. These lasers have a frequency offset between their intermode beat frequencies, with one laser acting as a master and the other as a follower. The master laser is driven with a DC signal, but its drive input line oscillates with an AC component that follows the intermode comb lines. This AC component is tapped off and mixed with a reference frequency to create the necessary frequency offset for the follower laser. As a result, the frequency combs are phase-locked in one degree of freedom, allowing for frequency stabilization of the electrical signals obtained through multi-heterodyning.
