Wavelength stabilization of Fabry-Pérot tunable filter based wavelength-swept laser for dynamic fiber-optic sensors

Abstract

We presents a stabilization method for peak wavelength variation in wavelength-swept laser (WSL) by adjusting the offset voltage of the Fabry-Perot tunable filter with closed-loop control. We achieved the WSL output was stabilized with a maximum ± 0.035 nm peak wavelength range.
