| Abstract(in English) | Mismatching of mode field diameter (MFD) between input/output devices for few-mode fibers (FMFs) causes mode-dependent loss and deteriorates transmission quality in mode-division multiplexing. MFD of existing mode in a FMF can be measured by individually exciting each mode into the FMF; however, in case that modal crosstalk at a mode exciter is considerable, MFD could not be measured correctly. In this paper, we show an application of low-coherence digital holography as a technique for accurate measurement of MFD without mode exciters tailored for a specimen of FMFs. |
