ABSTRACT:
A wavelength tunable laser emission component includes on the same substrate an active emission section and a Bragg section that includes a waveguide in which is formed a plurality of individual Bragg gratings corresponding to particular Bragg wavelengths. The waveguide has an electro-absorbent structure, the subsections of the Bragg section each being voltage-controlled. The laser emission wavelength is tuned to one or other of the Bragg wavelengths of these subsections according to control voltages applied thereto.
