Researchers aim at 100 Gbits/s- plus lasers

A project underway at The University of New Mexico (UNM) is aimed at demonstrating that semiconductor laser devices can send data at a bandwidth speed of over 100 Gbits/s, with potential applications that could result in ten times the speed of current fibre optic networks. The project addresses the

energy-ecient high- speed optical data egress (exit) from a cryogenic environment to room temperature for further processing. “Ultra-high-speed (>100 GHz) on-chip modulation of integrated lasers is an important ‘holy grail’ for the ever-increasing demand for ultrafast communication,” Osiński concludes.

Newsroom website, author Sharon Steely quotes Prof. Osiński: “Development of inexpensive ultrafast chips operating at speeds exceeding 100 Gbits/s will have a huge societal impact by increasing the transmission capacity of fibre-based networks.” Osiński’s project explores the use of semiconductor ring lasers to provide

need for faster data transfer by increasing the speed at which signals are first generated to send through a fibre optic network.For the past two and half years, work has centred on numerical simulations of proposed devices. The laboratory work will be performed at UNM’s Center for High Technology Materials (CHTM). In a posting on the UNM

in Latin America through a scalable and high capacity optical network.” “The big data applications driving cutting-edge advances in research and education are placing unprecedented demand on underlying high-speed infrastructure networks,” said Alberto Barriento, Managing Director, Caribbean and Latin America, Coriant. “We are pleased to partner with Raylex and Grupo Binário to take REUNA’s DWDM network to a new level of performance and scalability with best-in- class optical transmission technology optimised for robust computing, simulation,

customer experience.” The new DWDM network upgrade will provide REUNA the ability to deliver more flexible and resilient high-speed services while optimizing its optical backbone network for best- in-class spectral eciency, terabit-level scalability, and programmable and automated end-to-end service activation. “The interconnection of NRENs is fundamental to boosting the quality and velocity of research from universities and scientific communities,” said Cleber Calegari, Director for Education Vertical, Grupo Binário. “REUNA is taking an important step toward interconnection of NRENs

network locations. REUNA is dedicated to the research, education and scientific communities throughout Chile and interconnecting them with its partners around the world. The REUNA backbone network today serves thirty five institutions including universities, research centres of excellence, and international astronomical groups. Sandra Jaque, Head of Technology, REUNA, commented, “We chose Coriant for the proven scalability and flexibility of the solution that will enable us to easily and cost-eciently adapt to the evolving capacity demands of our end-users while delivering a superior

Coriant has announced that the National Research and Education Network in Chile (REUNA) has selected the its hiT 7300 Multi-Haul Transport Platform to modernise the county’s DWDM backbone network. The solution, which is equipped with CloudWAve optics and is to be delivered in collaboration with Grupo Binário and local telecommunications systems integrator, Raylex, will enable REUNA to scale transmission up to multiples of 200G optical channels to support the increasing capacity demands of research and education applications and ensure the ecient, low latency transfer of massive quantities of data between

visualization, and other high-speed e-science applications.”
