Title: The Innovations of Bernard Defaut
Introduction
Bernard Defaut is a notable inventor based in Paris, France. He has made significant contributions to the field of opto-electronics, holding a total of 3 patents. His work focuses on processes and devices that enhance the functionality and efficiency of optical fibers.
Latest Patents
One of his latest patents is a process for aligning an optical fiber that forms part of an opto-electronic head. This innovative process allows for the centering of an optical fiber in an opto-electronic head or the fiber-holder of a head in an adapter between the head and optical cable. A specific clearance is maintained between the cover of the head and the main part of the fiber-holder. A tool equipped with micrometric screws is utilized to create permanent deformations on the periphery of the cover made from a ductile alloy, while dynamic measurements are employed to verify the results. In cases involving a fiber-holder in an adapter, a similar clearance is maintained, and a skirt made from a ductile alloy is deformed at specific points to achieve the desired alignment.
Another significant patent is for an opto-electronic coupling head and the method for fitting such a head. This coupling head can function as either an emission head, coupling a light-emitting diode to an optical fiber, or a reception head, coupling an optical fiber to a photodiode. The design includes a diode mounted on the base of a case for a semiconductor device, utilizing a cap that has been stamped and perforated at the top. The fiber holder features a shoulder that abuts against the edges of the opening made in the cap, and the electric welding of the cap to the base secures the fiber holder in place. The optical fiber is fixed in the axial opening of the fiber holder through a deposit of solder.
