Abstract
A wavelength-tunable laser emission device includes a cavity delimited by a first and a second Sagnac mirror. The cavity has an amplifying medium and a tunable spectral filter using the Vernier effect. The filter includes at least three resonant rings arranged in cascade, each resonant ring integrating a loop mirror with wavelength tunable reflectivity.
