  • Patent number: 11380663
    Abstract: An opaque dielectric carrier and confinement substrate is formed by a stack of layers laminated on each other. The stack includes a solid back layer and a front frame having a peripheral wall and an intermediate partition which delimits two cavities located on top of the solid back layer and on either side of the intermediate partition. Electronic integrated circuit (IC) chips are located inside the cavities and mounted on top of the solid back layer. Each IC chip includes an integrated optical element. Electrical connections are provided between the IC chips and back electrical contacts of the solid back layer. Transparent encapsulation blocks are molded in the cavities to embed the IC chips.

  • Patent number: 11322666
    Abstract: An optoelectronic device includes an emitter of light rays and a receiver of light rays. The emitter is encapsulated within a first encapsulation layer, and the receiver is encapsulated within a second encapsulation layer. An opaque layer covers the first encapsulation layer (encapsulating the receiver) and covers the second encapsulation layer (encapsulating the emitter). The first and second encapsulation layers are separated by a region of opaque material. This opaque material may be provided by the opaque layer or an opaque fill.
