Lensed fiber of Raysung

Raysung applies the most advanced mechanical processing method in the world for manufacturing lensed fiber. The company's cutting-edge technology holds independent intellectual property protection. Raysung is capable of manufacturing lensed fiber into a variety of different shapes that include spherical, tapered, wedge, angled wedged, beveled, etc. The geometrical parameters can be well controlled in order to reach the best performance. Coating and metallization are also available.

The specifications of Tapered Lensed Fiber 

The shapes of the light spot

Horizontal Far Field & Gaussian Fit

Vertical Far Field & Gaussian Fit

 2D Far Field                   3D Far Field

Features of lensed fiber:

• High coupling efficiency

• Various far field beam shapes available

• Metallization    

• Anti-reflection coating     

Applications of lensed fiber:

• DLB coupling

• Pump laser coupling

• SLD laser coupling

• High speed receive device

Applications Notes:

How do Lensed fibers work? Shaped/Lensed fibers work by focusing the light to improve the mode matching between a waveguide and the fiber. Normally we try to get a lensed that produces a Gaussian beam. Ideally the Lensed fibers should be made to precisely match the laser diode or waveguide characteristics. Be prepared to supply as much information as possible to help develop the ideal lenses.
