Electro-optical hybrid connector for transmitting high optical ratings and electrical signals

Abstract

An electro-optical hybrid connection assembly provides an optical connection of at least a first optical fiber and a second optical fiber and an electrical connection of at least a first electrical conductor and a second electrical conductor. The assembly includes a first connector and a second connector. The first connector includes a first ferrule that encloses the first optical fiber, a centering sleeve surrounding the first ferrule and projecting beyond at least one end of the first ferrule, and at least one electrical plug-in contact connected to the first electrical conductor. The second connector includes a second ferrule enclosing the second optical fiber, and at least one electrical plug-in contact connected to the second electrical conductor; wherein each of the two optical fibers has a plane fiber end aligned at right angles to the fiber axis and provided with an anti-reflection coating; and wherein in the assembled state of the two connectors, the second ferrule is inserted into the centering sleeve of the first connector such that: the second ferrule abuts against the centering sleeve or the second ferrule abuts against the first ferrule, the fiber ends are separated from one another by a gap, and the plug-in contacts of the two connectors are plugged into one another in an electrically conducting manner.

Description

technical field [0001] The invention relates to an optoelectronic hybrid connection device for the optical connection of at least first and second optical fibers and for the electrical connection of at least first and second electrical conductors. Background technique [0002] Longitudinal diode-pumped solid-state lasers stand out for their high efficiency and good beam quality. The ability to store a relatively large amount of energy also enables it to generate millijoule pulses with a pulse width of several nanoseconds through an optical switch inside the resonator. This means that such lasers are suitable for material processing. Especially for laser engraving, good laser beam quality is essential to obtain precise machining results. Generating a scatter-free laser beam from a solid-state laser requires a scatter-free pump beam. The latter arises in many cases from the following process: strongly scattered and inhomogeneous beam parameter products of a diode laser bar ...

Problems solved by technology

Typical coupling losses in the low power range of 1-2W of about 0.2dB in the case of single-mode fibers or multimode fibers with smaller core diameters are not tolerated in the optical high power range (power ≥ 10W)
