RESUMO
We report on the heterogeneous integration of electrically pumped InP Fabry-Pérot lasers on a SOI photonic integrated circuit by transfer printing. Transfer printing is a promising micromanipulation technique that allows the heterogeneous integration of optical and electronic components realized on their native substrate onto a target substrate with efficient use of the source material, in a way that can be scaled to parallel manipulation and that allows mixing components from different sources onto the same target. We pre-process transfer printable etched facet Fabry-Pérot lasers on their native InP substrate, transfer print them into a trench defined in an SOI photonic chip and post-process the printed lasers on the target substrate. The laser facet is successfully butt-coupled to the photonic circuit using a silicon inverse taper based spot size converter. Milliwatt optical output power coupled to the Si waveguide circuit at 100 mA is demonstrated.
