Mode-division multiplexed transmission with inline few-mode fiber amplifier.
We demonstrate mode-division multiplexed WDM transmission over 50-km of few-mode fiber using the fiber's LP01 and two degenerate LP11 modes. A few-mode EDFA is used to boost the power of the output signal before a few-mode coherent receiver. A 6×6 time-domain MIMO equalizer is used to recover the transmitted data. We also experimentally characterize the 50-km few-mode fiber and the few-mode EDFA.
متن کاملAdaptive frequency-domain equalization for the transmission of the fundamental mode in a few-mode fiber.
We propose and experimentally demonstrate single-carrier adaptive frequency-domain equalization (SC-FDE) to mitigate multipath interference (MPI) for the transmission of the fundamental mode in a few-mode fiber. The FDE approach reduces computational complexity significantly compared to the time-domain equalization (TDE) approach while maintaining the same performance. Both FDE and TDE methods ...
متن کاملAll-fiber few-mode multicore photonic lantern mode multiplexer.
The emergence of space division multiplexing (SDM) for ultrahigh capacity networks has heralded pioneering Petabit-class optical transmission systems. In parallel to novel SDM fibers, a new class of components to enable scalable, low-loss schemes for unlocking fiber capacity is being developed. In this work, an all-fiber mode selective photonic lantern mode multiplexer designed for launching in...
متن کاملRadiation-mode coupling loss in tilted fiber phase gratings.
We demonstrate that grating tilt is an important adjustable parameter that can be utilized in addition to the more familiar parameters of grating length and index change to tune the spectral shapes of fiber phase gratings designed to perform demanding filter applications through guided-mode to radiation-mode coupling loss. A comparison is made between calculated transmission spectra obtained fr...
متن کاملLong distance transmission in few-mode fibers.
Using multimode fibers for long-haul transmission is proposed and demonstrated experimentally. In particular few-mode fibers (FMFs) are demonstrated as a good compromise since they are sufficiently resistant to mode coupling compared to standard multimode fibers but they still can have large core diameters compared to single-mode fibers. As a result these fibers can have significantly less nonl...
