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.
