Abstract

A photonic chip includes an optical layer bonded, via a bonding interface, to a carrier, and a laser source having a waveguide encapsulated in an encapsulating sublayer of the optical layer, the waveguide having a first electrical contact embedded in the encapsulating sublayer. The photonic chip also includes an interconnect metal network forming a via that extends, in the optical layer, from the bonding interface to the first embedded electrical contact of the waveguide, the interconnect metal network having metal vias that electrically connect to one another metals lines that extend mainly parallel to the plane of the chip, the metal lines being arranged one above the other within the optical layer.
