A Fiber Coupler is a passive optical device used for branching and combining optical signals based on ratios or for splitting and combining signals based on wavelengths.
Known as optical couplers, optical splitters, fiber optic splitters, fused fiber couplers, optical branching, and fiber combiners, these devices operate without a power source and are essential in various optical applications.
Fiber Couplers are used for combining multiple inputs of light or branching a single input into multiple outputs and support connections with multiple inputs and outputs over a wide range of wavelengths (approximately 400nm to 2000nm).
Fiber Couplers use a fused and elongated portion with a smaller core diameter, causing light to spread within the cladding and bind to neighboring fibers. Adjusting the length and diameter of the fused extension creates couplers with different coupling ratios. Common ratios include 50:50, 75:25, 90:10, and 99:1.
WDM Couplers use the same structure as optical fibers and vary in transmission distance for combining or separating light with different wavelengths. Changing the diameter and length of the fused extension allows for the separation of light with different wavelengths.
Common types include 1×2 or 2×2 couplers, as well as 1×3, 3×3, 1×4, 1×8, 1×16, 1×32, 1×64, etc.
Types include single-mode couplers, multi-mode couplers, polarization-maintaining, polarization-independent, double-clad, and broad-bandwidth couplers. CWDM couplers are also common, as well as couplers designed for specific applications like fluorescence microscopy and semiconductor laser applications.
Fiber Couplers are made by fusing and elongating optical fibers, consisting of a core and cladding. The process involves heating, fusion, elongation, and packaging, with some products manufactured through mechanical branching and coupling for higher mechanical stress resistance.
