PHOTONIC CIRCUIT WITH ACTIVE HYBRID III-V SECTION ON SILICON WITH INVERTED SILICON TAPER

摘要

A III-V hybrid active section silicon or silicon-germanium photonic circuit includes 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.
