Darli Mello studied Electrical Engineering at the RWTH?Aachen, Germany, and at the State University of Campinas (UNICAMP), Brazil, where he graduated in 2000. In 2002 he received the M. Sc. degree from the Institute for Communications Engineering (LNT) at the Munich University of Technology (TUM), Germany. During his master studies he carried out both experimental and theoretical work at the Siemens research labs in Munich. In 2006 he received the Ph.D. degree from UNICAMP after research stays at the TUM and at the California Institute of Technology (Caltech). After his Ph.D. studies he spent one year with Padtec Optical Components and Systems as a senior technology engineer. From August 2008 to March 2014 he was with the Electrical Engineering Department (ENE) of the University of Brasilia (UnB) as Assistant Professor. He is now an Assistant Professor at the Communications Department (DECOM) of the School of Electrical and Computer Engineering (FEEC), University of Campinas (Unicamp). His main reseach interests are optical transmission and networking. Darli Mello was part of subcommittee N3 of OFC (Network Architectures, Techno-Economics and Design Tradeoffs) from 2013 to 2016.

The new digital services that have become popular in recent years, such as video streaming, cloud computing, and group video calling, have generated a significant increase in the demand for data transmission. Transport networks, which enable channel flows at high transmission rates between different regions of a city or between cities, are especially impacted. To meet this demand, it is n…
Traffic generated by the internet has grown at the rate of about 100% a year since it was first measured, but has dominated the communication networks since the turn of the century. The networks prepared for this critical moment with the deployment of a large optical infrastructure, initially over-dimensioned. The advent of the WDM technology started a drive towards bandwidth mining, whic…
Recently, optical communications systems have advanced quickly thanks to the combination of coherent detection and digital signal processing. These new optical transceivers are able to flexibly adjust parameters such as code rate, modulation format and symbol rate. At the same time, intensive research efforts have attempted to increase the optical fiber capacity by means of space division…
Current high-capacity coherent optical systems implement wavelength multiplexing and polarization multiplexing, supporting the massive transmission of Internet traffic. However, new multiplexing and device integration techniques are required to sustain the exponential growth of traffic and avoid the consequent increase in costs per bit. In this scenario, space-division multiplexing (SDM) …
The evolution of the demand for inter- and intra-datacenter data traffic requires solutions of fiber-optic communication systems that are energy efficient, maintaining the trend of reducing the cost per transmitted bit. Space-Division Multiplexing (SDM) is a promising solution, if not the only one, capable of meeting these requirements. In this technique, distinct signals are simultaneous…
The popularization of the Internet broadband access enhances the perspectives of exhaustion for the legacy optical fiber infrastructure. In this context, the research of mechanisms which increase the capacity and reach of wavelength division multitiplexing (WDM) based optical systems is a timely issue. This post-doctorate project approaches three essential topics related to very high capa…
In the near future, the exponentially increasing demand for higher data rates will exceed the capacity of current coherent optical systems employing wavelength-division multiplexing (WDM). Once the physical dimensions of polarization, amplitude, phase, and frequency are exhausted, exploring the space dimensionemerges as an attractive solution to overcome this capacity limit. Space-divisio…
Submarine fiber systems carry nearly 95% of the data traffic between different countries and continents. These systems use space-division multiplexing (SDM), which is currently implemented by several single-mode fibers in parallel. To increase the spatial information density and enable compact scaling of components, multi-core and multi-mode fibers are interesting alternatives for the fut…
