Abstract
A wavelength tunable laser emission device () comprises: a first waveguide () comprising an optical amplification means for producing a stimulated light emission, the first waveguide extending in a longitudinal direction of the emission device, a second waveguide () made of silicon on silicon dioxide and disposed parallel to the first waveguide spaced from the first waveguide in a vertical direction of the emission device so as to allow the existence of a hybrid optical mode coupled at one and the same time to the second waveguide and to the first waveguide, the second waveguide comprising a distributed reflector () along the second waveguide, the second waveguide comprising transverse zones () doped differently so as to form a polar junction oriented in a transverse direction of the emission device. Electrodes () coupled to the doped transverse zones modify an effective index seen by the hybrid optical mode.
