An optical system with an optical beam propagation extension, having an input and an output for the optical beam. The system includes at least two optical reflection elements for reflection of the beam, arranged to extend the propagation of the beam by reflection on the reflection elements, and at least one optical beam transmission element arranged to be traversed at least twice by the optical beam in different directions during propagation of the optical beam in the optical system.

Abstract:
This assembly of an object and a support is achieved by using solder bumps. At least two wettability areas are made respectively on object and on support. Each solder bump ensures electrical contact and mechanical fixing firstly to one of the wettability areas of object and secondly to one of the wettability areas of support. The melting temperature of solder bumps is lower than the melting temperature of each of the wettability areas. Each wettability area of object forms an angle of 70° to 110° with respect to each wettability area of support. Object and support are mutually distant.

Abstract:
A hermetic coupling device between an optoelectronic component emitting and/or receiving a light beam, and an optical transmission mechanism conveying the light beam. The hermetic coupling device includes a substrate including a blind hole, having a bottom wall, into which one part of the optical transmission mechanism is inserted. The substrate is formed of a stack of a first layer and a second layer. The light beam crosses the substrate passing through the bottom wall of the blind hole, the substrate receiving the optoelectronic component substantially opposite the blind hole. Reflective patterns are inserted between two layers of the hermetic coupling device, substantially on the periphery of the blind hole, and reflect one part of the light beam emitted by the optoelectronic component.
