| 摘要 |
The invention relates to a coupling arrangement for non-axial transfer of electromagnetic radiation from at least one feeding fiber (2) into a target fiber (20) in a transfer region via an intermediate fiber (6), wherein
a. said intermediate fiber (6) comprises an input end (8) and a converging taper portion (16),
b. said input end (8) of the intermediate fiber (6) is spliced to an output end (4) of the feeding fiber (2) in an axial way,
c. the converging taper portion (16) of said intermediate fiber (6) is fused to the target fiber (20) in the transfer region in a non-axial way,
characterized in that said intermediate fiber (6) has a non-circular cross-section, such as a polygonal, in particular a hexagonal or an octagonal cross-section. |
