Abstract
A device for establishing optical connection links between electronic component cards forming part of a package. The device comprises a transparent plate having parallel faces and a light source which emits a divergent beam and is implanted on a first card. The beam is reflected from a first optical diffracting element in the form of a collimated beam which undergoes multiple reflections from alternate reflecting elements to a second optical diffracting element and is converted by the second element to a convergent beam transmitted to a detector which is implanted on a second card.
