A wavelength tunable laser emission device (1) comprises: a first waveguide (31) 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 (5) 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 (9) along the second waveguide, the second waveguide comprising transverse zones (11, 12, 13, 14) doped differently so as to form a polar junction oriented in a transverse direction of the emission device. Electrodes (15, 16) coupled to the doped transverse zones modify an effective index seen by the hybrid optical mode. |

1. A wavelength tunable laser emission device (1), comprising:
a first waveguide (31, 131) 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 (5, 105) 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 (9, 109) along the second waveguide beneath the first waveguide, the second waveguide comprising transverse zones (11, 12, 13, 14; 111, 112, 113, 114, 46, 47, 48) doped differently so as to form a polar junction oriented in a transverse direction of the emission device, first electrodes (35, 36; 135, 136) coupled to the first waveguide for injecting a pumping current into the optical amplification means, and second electrodes (15, 16; 115, 116) coupled to the doped transverse zones of the second waveguide so as to modify an effective index of the second waveguide seen by the hybrid optical mode. |
