Spatially dispersive scheme for transmission and synthesis of femtosecond pulses through a multicore fiber
2012
Optics Express
A dispersive device divides the input pulses into spatially separated spectral components which are individually launched in the different channels of a multicore fiber before being recombined at the output ...
Both are reported in a proof of concept experiment using 190 fs input pulses and a 5 cores polarization maintaining fiber. Extension of the concept to femtosecond pulses amplification is suggested. ...

Predictable and unpredictable phenomena in optical fibers for space-division/mode-division multiplexing transmission: statistical analysis of coupling and mysterious behavior of modes
2020
IEICE Electronics Express
However, the origin and behavior of crosstalk are different in SDM using multicore fibers (MCFs) and in MDM using few-mode fibers (FMFs). ...
The transmission capacity of single-mode single-core fibers is approaching the limit of about 100 Tbps owing to nonlinearity and the fiber fuse, which limit the input signal power. ...
After joining the EXAT Research Initiative, which has been carried on into the EXAT Research Group of IEICE, we studied the characteristics of optical fibers for SDM and MDM transmission. ...
