MULTIMODE POWER COMBINER WITH SIGNAL FEEDTHROUGH
Tapered Fiber Bundle
Gooch & Housego’s tapered fiber bundle series power combiners provide a high efficiency means of combining light from several multimode sources into one fiber.
G&H proprietary manufacturing techniques allow the precise fusion of input fibers around a central signal feedthrough fiber and a dual clad output fiber providing high coupling efficiency over a wide pump wavelength range.
Available in a standard (6+1)x1 configuration, the combiner can be fabricated from a range of industry standard fibers for ease of splicing to commercially available laser diodes and fiber applications.
Custom options cover large mode area (LMA) signal feedthrough fibers, dual clad output fibers and port count/configurations and are available on request.
Please contact the sales team for further information.

Order code
Order codes are comprised of a standard device prefix (e.g. TFB) followed by code letters or numbers which correspond to available options.
Sample: TFB-550611B30 (6+1x1 tapered fiber bundle, 1550 nm signal input, 6 pump inputs 105/125 µm 0.15 NA fiber, 1550 nm core DCF output, high power housing, 0.5 m pigtail lengths).
1 Signal wavelengths of 1064 nm or 1550 nm assume the use of Corning Hi1060 or SMF-28 (or equivalent) fibers respectively.
2 Typical core diameters are based on ~4 µm for 1064 nm and ~8 µm for 1550 nm. Fibers are passive.
3 Maximum housing lengths. Note- Adequate heat-sinking is required for high power operation. See high power multimode combiner application notes (PEC 0134) on website or consult sales office.
4 Minimum pigtail lengths.
