Verbindertechnologie für hohe Leistungen

DIAMOND nutzt für Power Solution (PS) Verbindungen verschiedene Strahlaufweitungsmethoden (Expanded Beam, kurz EB) je nach Anwendungsbereich.

Die wichtigsten Arten der Strahlaufweitung können wie folgt definiert werden: gespleisste GRIN-Linse, Kugellinse sowie gespleisster Glasstab oder Endkappe.

PS Collimated (Contact)

The method of splicing a GRIN (gradient index) lens to expand a beam has been used by Diamond for more than ten years to improve power handling. A GRIN lens is spliced at the end of a SM fiber and its length is polished to result in a collimation of the SM beam. Two such connectors when mated achieve an exceptionally low IL.

PM-PS Collimated Polarization Maintaining (Contact)

Polarization plays an important role in the industrial photonics market and when coupled with medium-high power application, creates a market of high criticity. Sensors and communication systems have been designed using Polarization Maintaining or Polarizing fibers. Special connectors are required for such application, because their connection must be made with a certain orientation. Only connectors with an orientation key are capable of properly terminating these fibers.

PSm Power Solution Multimode (Contact)

No standards for large MM connectors has been defined with high power application in mind. The quality of the contact is critical and standard SM fiber optical interface is not sufficient. Diamond has established a new Optical Interface, the PSm, to fill this void and help end-users to dispose of reliable connectors for these applications. The optical interface used 100% concentricity measurement control and optical geometry measurements. A special visual inspection completes the Optical Interface definition.

PSf Free Space (Diverging)

A glass rod can be spliced at the end of a SM fiber. This allows the beam to be expanded before it exits the glass, diminishing the power density at the glass-air interface. This technique is used for high power application, at the injection or at the output in order to minimize the risk of burns at the interface.

PSb Ball lens

A ferrule is placed behind a ball lens which is glued to a housing. Depending on the concentricity, the expanded beam exits the lens at a particular angle. To minimize the exit beam angle, Diamond uses the ACA process.

PSl Lensed (Focused)

Diamond offers focused beam on a customer requirement base. Using Diamond mature PS technology (based on GRIN lens), a focused beam optimized for free space light transmission, can be designed and manufactured upon request. This technology is especially used for measurements (interferometric) and for sensing.

PSi Free Standing

The fiber-end free from epoxy glue allows a proper thermal dissipation in the region of maximum power density. A proprietary design mode-stripper can be integrated to obtain laser power confinement in the fiber core. The amount of power stripped out from the cladding is a function of the laser Beam Product Parameter (BPP) and of the receiving fiber core diameter and numerical aperture (NA).

PSc Collimator Systems

Collimators are for use in a wide variety of optical systems. These modules are designed to collimate or focus light exiting an optical fiber to a desired beam diameter or spot size a specific distance away. Collimators are used with laser diodes, photodiodes, acoustic-optic modulators and other fiber optic devices where a specific output is needed.
