What is a pump and signal combiner used for?

Pump and signal combiners are being used in a wide range of applications, such as fiber laser and amplifier, telecommunication in industrial and biomedical areas, metrology, life science, imaging, quantum optics, and more.

To better understand a pump and signal combiner, you need to learn about pump combiners.

What is a Pump Combiner?

A pump combiner is originally a fiber-optic coupler designed to send pump and signal light into a fiber laser or fiber amplifier. It also goes by another name called pump couplers.

Certain fiber optic devices such as high-power fiber lasers and amplifiers are based on rare-earth doped double-clad fibers. In such devices, you can inject pump and signal light into such a fiber by simply focusing the light onto a bare fiber end.

The same thing is done for fiber amplifiers and fiber laser devices in the research stage. Industrial lasers are best if they are an all-fiber setup, where fiber-coupled pump laser diodes are directly connected to the active fiber via some passive transmission fibers, avoiding any air spaces in the path of the light signal.

When using multimode optic fibers, one needs fiber-optic pump combiners as they facilitate better robustness and stability of devices.

Some pump combiners can safely handle multiple kilowatts such as 10W or 30W, and they are called high-power pump combiners.

What is a pump and signal combiner?

A pump and signal combiner has two interfaces. On one interface, a fiber can be connected to a certain type of active fiber directly by using the fusion-splicing technique. Sometimes, there is an additional passive fiber between these two fibers to include a fiber Bragg grating if that cannot be written into an active fiber.

On the other interface, the combiner has several input multimode fibers that can be connected to fiber-coupled pump laser diodes. In addition, there is another single-mode fiber or a few-mode fiber for injection or extraction of the signal light. Though no signal light needs to be injected in the the case of a fiber laser, laser light needs to be extracted from one end.

Thus, when a pump combiner also has an additional fiber for signal light extraction or injection, it is referred to as a pump and signal combiner.

An (N+1) x1 pump and signal combiner can combine or couple N pump lasers and 1 signal channel into one fiber and create a high-power pump laser source.

What are the uses of pump-and-signal combiners?

The applications of pump and signal combiners have become very diverse and seeing even more expansion. Some of the most important uses and applications of pump and signal combiners are:

  • Pumping of fiber lasers and amplifiers
  • Pumping of fibers with multiple cores and large mode areas
  • Pump combiner for elements Nd, & Yb,  & Er & Ho & Tm-fiber
  • Metrology
  • Life science
  • Quantum optics
  • Gravitational wave detection – Atom cooling and trapping
  • Imaging
  • Industrial telecommunication
  • Biomedical and more

Pump Combiners: Types and Properties You Should Know About Before Placing an Order

Pump Combiner is a passive component, widely used in different applications such as fiber laser, fiber amplifier, high power EDFA, biomedical systems, sensor systems, and more. They are made using the Fused Biconical Taper (FBT) technique. According to their design principle, several pump fibers are arranged around a signal fiber and the whole bundle that is typically surrounded by a glass tube is tapered down in a way that its dimensions align perfectly with that of the active fiber.

Pump combiners are available in three different constructions, namely:

  • Multimode NX1
  • (N+1)x1 Pump and Single-mode Signal Combiners
  • (N+1)x1 Pump and PM Signal Combiners                                                                             
  1. Multimode Pump Combiners

Multimode Pump Combiners are usually the ones that couple 7 or 19 multimode sources directly into cladding-pumped fiber. They combine the optical power from different optical fibers to create a high power output.  

Multimode combiners facilitate highly efficient power transfer to cater to the needs of high-power applications like direct diode material processing and pump cascading while ensuring maximum brightness conservation.

The main applications of multimode pump combiners are fiber lasers, fiber laser combination, industrial, and research. They are available in different configurations of N x 1, such as 2×1, 3×1, 4×1, 7×1, 19×1, 37×1, and so on.   

  • (N+1)x1 Pump and Single-mode Signal Combiners

These types of combiners are designed to couple 6 or 18 multimode sources and 1 SM signal source either to provide a combined power output or to use with a cladding-pumped fiber.

In other words, single-mode combiners are those pump combiners where the signal input is transferred via a single-mode fiber and not the pump inputs. Pump inputs are typically used in multimode pump combiners.

The signal-fiber design is often used in the military and medical industries. It can also be used to design an amplifier for use in telecommunications.

  • (N+1)x1 Pump and PM Signal Combiners          

These combiners are built to couple 6 multimode sources and 1 polarization-maintaining (PM) source to produce combined power output or be used with a PM cladding-pumped fiber. Polarization-maintaining combiners are said to possess polarization-maintaining properties for the signal only.

Just like other pump combiners, they are also used to design amplifiers that require signal polarization outputs for use in industrial, military, medical and telecommunications applications.

Key Properties to Look for in Quality Pump Combiners

  • The diameters of fibers should be the same to ensure high-quality fusion splicing with the proper matching of core positions.
  • The pump fibers must have high compatibility with fibers of pump laser diodes. The core diameter and numerical aperture must be at least as high as those of pump diodes’ pigtails. While larger values of pump input fibers don’t affect power coupling efficiency, it might mean that the pump brightness won’t be utilized fully.
  • The intensity profile of the fundamental signal fiber mode should match the fundamental mode of the active fiber core. It will help you couple signal light into the fundamental mode efficiently.
  • The pump light should suffer minimum losses when propagating through the combiner. It will help ensure a coupling efficiency higher than 90 percent and minimized thermal damage.
  • In a pump or signal combiner, there should be only a minimal loss of brightness.
  • The combiner should withstand the intended optical power levels.

Whenever you buy pump combiners, keep all these factors in mind to ensure that you make the right choice. Besides, you also have the freedom to order customized pump combiners. So, if you don’t find the pump combiner you are looking for, don’t hesitate to get in touch with the manufacturer and discuss your requirements.
