Welcome to the Lightwave Research Laboratory

Our Research Mission

The Lightwave Research Laboratory, led by Professor Keren Bergman, aims to investigate the realization of dynamic optical data routing in transparent optical interconnection networks, developing potentially disruptive technology solutions with ultra-high throughput, minimal access latencies, and low power dissipation that remains independent of data capacity, ultimately capitalizing on the enormous bandwidth advantage enabled by dense wavelength division multiplexing.


Join Our Research Group

If you are interested in joining our research group, we offer numerous undergraduate, graduate, and post-graduate research opportunities.

Professor Keren Bergman Wins IEEE Photonics Engineering Achievement Award

The IEEE Photonic Society presented the 2016 Engineering Achievement Award to Keren Bergman, Chalres Batchelor Professor and Chair of Electrical Engineering. The award was presented at the IEEE Photonics Conference and is given in recognition of an exceptional engineering contribution that has had a substantial impact on the development of laser or electro-optic technology or the commercial application of technology within the past 10 years. Professor Bergman was selected for her extraordinary work in "optical interconnect networks and photonic-abled architectures that advance communication and computing systems."

"Combing Through Streams of Light"

After almost a decade of long-distance collaborations, Keren Bergman, Michal Lipson, and Alex Gaeta are working together in one place, here at Columbia Engineering. Lipson and Gaeta joined the School this summer as the Eugene Higgins Professor in Electrical Engineering (EE) and the David M. Rickey Professor of Applied Physics and of Materials Science, respectively. And now, together with Bergman, who is the Charles Batchelor Professor and EE chair, the trio is set to break new ground in nanophotonics, or, as Lipson, a preeminent leader in nanophotonic fabrication, puts it, "optics on a very, very small scale."

AIM Photonics

Columbia Engineering's photonics experts, including Professors Keren Bergman, Michal Lipson, and Alex Gaeta, are an integral part of an exciting new Integrated Photonics Manufacturing Innovation Hub in Rochester, NY, announced by Vice President Joseph Biden at a press conference on July 27. In winning the bid, the NY-led consortium captured the largest federal investment--over $610 million, with $110 million in federal funds, and more than $500 million in non-federal contributions--to date under the Obama administration's National Network for Manufacturing Innovation.
