    摘要: In an optoelectronic module (1) comprising a plastics material package (2) accommodating a base (8) fixed to the package (2) and supporting an optical component (9) coupled by an optical fiber (5) to an optical connector (4) of the package (2), fiber displacements associated with thermal stresses are avoided by mounting the base so that it floats on the package (2) and possibly the connector (4). The floating mounting of the base (8) is obtained by using for fixing the base one or more adhesives (13, 14) having a greater elasticity than the adhesives used to fix each of the two ends (6, 7) of the fiber (5) to the base (8) and the connector (4), respectively.

    摘要: A four-port optical circulator has two planar lightwave circuit polarisation beam splitters (40, 54). Two ports of the circulator are formed by two input ports (32, 36) of the first splitter (40). The two other ports of the circulator are formed by two input ports (34, 38) of the second splitter (56). The circulator further has an assembly of a wave plate (46) and a Faraday rotator (48). A first light path through this assembly connects a first output port (42) of the first splitter (40) and a first output port (50) of the second splitter (54). A second light path through the assembly connects a second output port (44) of the first splitter (40) and a second output port (52) of the second splitter (54). The circulator is easy to integrate into a planar lightwave circuit. It may also be used as isolator.

    摘要: In a method of coupling an optical fiber to an optical component on the same substrate, eccentricity of the core of a coupling fiber is exploited to adjust the vertical position of the core by rotation of the fiber about its axis. This adjustment is carried out with the fiber held in contact with a horizontal reference surface of a substrate also carrying a laser diode constituting the component to which the fiber must be coupled. The method can be used to implement transmission headers for optical fiber telecommunication systems.

    摘要: An optical fiber (F) and a laser (L) are fixed on the top faces of two bases (EF, EL) which also have two facing vertical faces. A spring (4) presses these two faces against each other so as to create thrust friction. The thrust force is initially moderate in order to enable the relative vertical and transverse positions (GV, GT) of the two bases to be adjusted smoothly, after which the force is increased progressively in order to prevent relative displacement taking place while the two bases are being welded together by means of a YAG laser. The invention is particularly applicable to making optical transmission heads usable in optical fiber telecommuncations systems.

    摘要: A process of aligning electro-optical devices that associate a semiconductor, laser diode or electroluminescent component with an optical component, such as an optical fiber. These devices must be aligned with a precision of from .+-.1 to .+-.10.mu.. The semiconductor component is integral with a centering part through the intermediary of a first bracket. The optical component, through the intermediary of a second bracket, is integral with a container in which is placed a hardening material. The centering part is plunged in the hardening material, with three degrees of mobility. The alignment is dynamic. When adjustment has been made, the hardening material is rapidly and rigidly fixed.
