A photonic chip including an optical coupler capable of transferring an optical signal between a first waveguide made of III-V material and a second waveguide made of silicon, this optical coupler including a first extension made of III-V material which extends the core of the first waveguide, a second extension made of silicon which extends the core of the second waveguide, and a SiGe inclusion buried inside of the second extension, this inclusion being made of SiGe whose chemical formula is SiGe, where x is in the range between 0.2 and 0.5, and being optically coupled, on a first side, to the first waveguide and, on a second opposite side, to the second waveguide.
