Mode Field Adaptor-Backward

Define large MFD to small MFD is Mode Field Adaptor-Backward,Mode Field Adaptors is designed to makes two fiber to keep mode field diameter matched with low fundamental mode signal loss and minimal degradation of beam quality (M2).

Category:

Mode field is different in fibers with different core diameter and NA. Splicing loss is large between two fibers with different mode field. In order to reduce splicing loss, mode field must be similar. MFA can optimize splice loss significantly, usually <0.5dB, even <0.3dB between different fibers.

Mode Field Adaptors is designed to makes two fiber to keep mode field diameter matched with low fundamental mode signal loss and minimal degradation of beam quality (M2).These devices can also be used to absorb residual pump light in the reverse direction, preventing damage to the seed or isolator.

Define small MFD fiber to large MFD fiber is F-Forward, large MFD to small MFD is B-Backward.Custom Mode Field Adaptors can be designed to meet a wide range of fiber types.
