Abstract
A photonic transmitter is provided, including a laser source including a first waveguide made of silicon and a second waveguide made of III-V gain material, the waveguides being separated from each other by a first segment of a dielectric layer; and a phase modulator including a first electrode made of single-crystal silicon and a second electrode made of III-V crystalline material, separated from each other by a second segment of the dielectric layer, where a thickness of the dielectric layer is between 40 nm and 1 μm, where a thickness of a dielectric material in an interior of the first segment is equal to the thickness of the dielectric layer, and where a thickness of the dielectric material in an interior of the second segment is between 5 nm and 35 nm, a rest being formed by a thickness of semiconductor material.
