III-V hybrid active section photonic circuit on silicon to type inverted silicon

摘要

The invention relates to a silicon or silicon-germanium III-V hybrid active section photonic circuit, which comprises a III-V heterostructure amplifier medium (1, QW, 2) and an optical waveguide. The waveguide comprises a coupling section (31) facing a central portion of the amplifying medium, a propagation section (34, 35) and a modal transition section (32, 33) arranged between the coupling section and the propagation section. In the modal transition section, the optical waveguide is gradually widened from the propagation section to the coupling section. Figure for the abstract: Figure 1
