Patent ID: 7476041

Claim:
A hermetic coupling device between at least one optoelectronic component, which is to emit and/or receive at least one light beam, and an optical transmission means which is to convey the light beam, comprising: a substrate including at least one blind hole, having a bottom wall, in which one part of the optical transmission means is to be inserted, the substrate formed of a stack of at least one first layer and of at least one second layer to be arranged between the first layer and the optoelectronic component, the first layer having the blind hole of the substrate passing fully through it, and the second layer forming the bottom wall of the blind hole of the substrate, the light beam having to cross the substrate passing through the bottom wall of the blind hole, the substrate configured to receive the optoelectronic component substantially opposite the blind hole, and comprising reflective patterns inserted between two layers of the hermetic coupling device, that are arranged substantially on the periphery of the blind hole and configured to reflect one part of the light beam emitted by the optoelectronic component.
