Lensed Fiber and Assembly

K Lab supplies a variety of standard and custom lens-tipped fibers that eliminate the need for using separate lenses. The tip of the fiber is formed into a variety of lens such as wedge, cone, and angled shape. K Lab also offers the whole fiber assembly with propriety ferrule mounted on bare fiber with non-organic adhesive sealing.  No metal coating on fiber tip is required for the mounting.  As a result, we simplify the process, at the same time we eliminate the stress that could be introduced on fiber due to metal deposition and soldering. 

Key Benefits

Lensed Fiber provides

  • High efficiency coupling for applications that power delivery is very critical
  • Available for PM, single mode and multi-mode fibers
  • Optimized coupling for cost effective packaging choices 
  •  
  • Applications include: fibers for high power laser pump and SLD modules in medical, industrial and telcommunication applications.

     

    Type of Fiber: PM fiber, single mode fiber, multimode fiber

    Type of lense: wedge, cone, angled.

    High efficiency coupling:  75-80% coupling for typical edge emitting lasers

    Cost efficient coupling:  50-70% coupling for typical edge emitting lasers

    Focal length:   5-10 mm from fiber tip

    Additional coatings: AR coating service and fiber metalization service can be provided as well as whole fiber assembly service.

Fiber assembly provides

  • Low stress on fiber for no-metal-soldering processing
  • Non-organic sealing method between fiber and ferrule
  • Convenient, robust handling capability
