The scheme is to fuse a small section of fiber with small mode field diameter (MFD) to the single-mode fiber array, converting the larger MFD in the fiber to the smaller MFD that can be coupledSee more on meisuoptics ScienceDirect
When an input optical signal is introduced with sufficiently low power levels (i.e., at linear regime), they can divide themselves equally and directs them through the output channel as well as it can combine
Generally, coupling light from a well-collimated laser source into a multimode fiber is not a difficult problem. If the user assures that the maximal ray of the focused

Dichroic couplers can be used to combine a pump and a signal input for a fiber amplifier, or to remove residual pump light after the amplifier. For high-power
Fiber optic couplers are optical devices that connect three or more fiber ends, dividing one input between two or more outputs, or combining two or more inputs
Optical fiber coupling refers to the process of joining optical fibers to split or combine light with minimal loss, utilizing methods such as fusion splicing, mechanical splicing, or connectors. The efficiency of

In addition, since the misalignment tolerance of edge couplers is comparable with the fabrication tolerance of fiber arrays, edge coupling is only
Fiber couplers are fiber devices for coupling light from one or several input fibers to one or several output fibers, or from free space into a fiber.
