An optical device (5) for generating a combined multi-wavelength optical signal (6) comprises:
€¢ at least two mode-locked laser components (10), each mode-locked laser component (10) being able to generate an optical comb (13A, 13B) having a spectrum formed of a plurality of wavelengths with constant frequency spacing, the spectra of the generated optical combs (13A, 13B) being shifted, the frequency spacing values of said spectra being equal,
€¢ means (12) for superimposing the generated optical combs (13A, 13B), said means (12) being connected to an output of each of the mode-locked laser components (10), said means (12) having an output (20) adapted to provide the combined multi-wavelength optical signal (6) formed of the superimposition of the generated optical signal combs (13A, 13B). |
