Andrew Chraplyvy and Robert Tkach, Alcatel-Lucent Bell Labs scientists, will share the 2009 Marconi Fellowship and Prize for their research into optical fiber nonlinearities and their development of novel mitigation techniques that vastly increased the transmission speed and capacity of optical fiber communications systems. Their research and unique innovations are at the core of today’s high speed broadband telecommunications networks.

The Marconi Fellowship and Prize is awarded yearly by the Marconi Society honoring a living scientist whose work in the field of communications and information technology advances the social, economic and cultural improvement of all humanity.

Realizing the Future of Optical Networking

Chraplyvy and Tkach, partners in research for more than two decades, recognized that demand for network capacity was growing exponentially and that nonlinearities inherent in optical transmission would make it virtually impossible to achieve the speeds required to meet that demand. The two scientists recognized that previous approaches to increase transmission efficiency were not sufficient and they developed novel techniques that would overcome these limitations.

Working with other Bell Labs technologists, Chraplyvy and Tkach helped to devise a new type of optical fiber with precisely controlled chromatic dispersion that would be able to dramatically increase transport capacity by supporting large numbers of wavelengths for carrying high-speed signals. This new fiber (branded TrueWave® Fiber) optimized transmission capacity of communications networks and is today known generically as Non-Zero Dispersion Fiber (NZDF). NZDF fiber has become an industry standard that has enabled the explosive growth in communications bandwidth. To date more than 50 million miles (80 million kilometers) of this fiber have been installed globally.

“Over the course of their careers Andy Chraplyvy and Bob Tkach have not only made numerous breakthroughs that have revolutionized optical technology, but in the process have improved the research of others and made the organization successful through unfailing collaboration, passion, and inventiveness,” said Rod Alferness, Bell Labs Chief Scientist.  

The pair will receive the award at the annual Marconi Awards Dinner hosted by the Bologna-based Fondazione Guglielmo Marconi at the Palazzo Re Enzo in Bologna, Italy on October 9th.
