Product Description

Custom Coupler 980nm Large Core Multimode Taper
Product Description
A multimode taper coupler, also known as a multimode waveguide interference (MMI) coupler, is a device that can split or combine power in optical circuits. They are often used in Mach-Zehnder interferometers and optical switches.
Here are some things to know about multimode taper couplers:
  • Tapering
    Tapering is the process of gradually narrowing or thinning an object, like a pencil tip. Tapered optical fibers are large optical fibers that have been reduced in size. 
     
     
     
  • Fused biconical taper
    This is a common method for manufacturing multimode optical fiber couplers. It involves fusing stripped fibers together while applying heat and stretching them. 
     
     
     
  • Fiber core diameter
    Multimode fiber cables have a larger core diameter than singlemode cables, which allows more signals or light rays to travel through at once.
