Abstract:
1. An optical electronic package, comprising: a substrate wafer having a front face and a rear face; a transmitting integrated circuit chip having a rear face fixed to the front face of the substrate wafer and comprising, in a front face, a light radiation optical transmitter; a receiving integrated circuit chip having a rear face fixed to the front face of the substrate wafer and comprising, in a front face, a first light radiation optical sensor; a transparent encapsulation structure comprising a transparent plate extending directly over said first light radiation optical sensor and directly over said optical transmitter and a transparent encapsulation block which extends between the rear face of the transparent plate and the front face of the receiving integrated circuit chip and between the rear face of the transparent plate and the front face of the substrate wafer, embedding the transmitting integrated circuit chip; and an opaque encapsulation structure formed by an opaque encapsulation block extending over the front face of the transparent plate and having a front through opening which reveals a front area of the transparent plate, this front area being situated above the optical transmitter of the transmitting integrated circuit chip and offset laterally relative to the first light radiation optical sensor of the receiving integrated circuit chip.
