980nm Large Core Multimode Taper Coupler for Fiber Optic Communication Systems
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.
Features
- High Directionality
- Low Insertion Loss
- High Stability & Reliability
Applications
- Fiber Sensors
- Fiber Optic Communication Systems
