Abstract:
1. Laser emission device with integrated light modulator comprising: a multilayer waveguide, the waveguide extending along a longitudinal direction of the device, the waveguide comprising, on a support layer made of silicon dioxide, the waveguide comprising, along the longitudinal direction the device also comprising: wherein the device also comprises: wherein the first guiding layer, the first doped layer, the second guiding layer, the second doped layer and the positive first electrode form a narrow ridge in the transition section, the narrow ridge being narrower than the first doped layer in the laser amplification section and the light modulation section, such that the first doped layer forms a first resistive channel of small bulk between the third electrode and the fourth electrode in the transition section, wherein the second doped layer comprises an electrical insulation situated in the transition section of the waveguide to form a second resistive channel between the first electrode and the second electrode in the second doped layer, in which the electrical insulation is obtained by a protonated insertion zone of the second doped layer, and the first resistive channel exhibits a resistance of between 1 and 10 kΩ, which makes it possible to independently apply the DC voltage to the laser amplification section and the modulation signal to the light modulation section.
