Nonlinear Effects in Multi-Core Fibers

Keywords:
nonlinearity, optical communications, mcf, multicore fibers

Description

Space-division multiplexing (SDM), which consists in exploiting multimode fibers (MMFs) or multicore fibers (MCFs) instead of single mode ones, is one of the future optical communications architectures to increase data rates and network planning flexibility. The nonlinear properties of MCFs are of primary interest in assessing the usefulness of SDM against the current network. With this thesis, the student has the chance to work on a state-of-the-art topic in the field of optical communication systems, and progress quickly thanks to a tight (if desired) supervision. Would you be curious to know more about it? If so, just get in touch with me at paolo.carniello@tum.de (personal page https://www.ce.cit.tum.de/lnt/mitarbeiter/doktoranden/carniello/).

Prerequisites

Strong Coupling Multimode Fibers

Keywords:
Multimode fibers, Space-division multiplexing

Description

Space-division multiplexing (SDM), which consists in exploiting multimode (MMF) or multicore fibers instead of single mode ones, is one of the future architectures to increase data rates and network planning flexibility. A desired working condition for SDM is the so called strong-coupling linear regime, which is however not intrinsically achievable in common MMFs. With this topic, the student has the chance to investigate if it would be achievable with some new design. If you are curious about it, just send a mail to paolo.carniello@tum.de.

Research Interests

Space-Division Multiplexing for Optical Fiber Communications

Today's commercial optical fiber network relies on single mode fibers for long-haul communications, so that only the two polarizations of the fundamental guided mode are excited through independent data streams. Space-Division Multiplexing (SDM) aims at exploiting the spatial (or modal) dimension for the transmission of information, thanks to the use of multimode fiber structures, like multimode or multicore fibers. Ideally, many of the already existing techniques for single-mode fiber transmission (like wavelength division multiplexing or high-cardinality modulation formats) can be extended to the SDM architecture. However, new linear and nonlinear impairments arise in this scenario, which need to be modeled, analyzed, and, possibly, compensated. 

My current research is focused on physical models for optical signal propagation, from the nonlinear Schrödinger equation for multimode structures, to the different flavors of Manakov equations. I am curious about simplified numerical and analytical models for the signal propagation in multimode structures, and, for future research, in possible DSP and optical compensation techniques for linear and nonlinear impairments. I am developing a simulator based on a numerical solver for system level analysis for the SDM architecture.

Finally, I am interested in understanding which multimode fiber geometries could better suit the different SDM scenarios, depending on the linear coupling regimes and on the significance of nonlinear effects.

If you would like to work together, feel free to contact me!
