Our research group led by Dr. Dan Kilper investigates the dynamics of transparent optical networks, developing potentially disruptive technology solutions with ultra-high throughput, minimal access latencies, and low power dissipation. We are developing new ways to control optical systems through software so that the high capacity of optics can be used for a wide range of emerging applications in smart cities, the Internet of Things, and 5G mobile networks. Novel integrated photonic devices promise to drive down the cost and expand the functionality available to optical networks and our group is inventing the architectures and methods to realize these benefits in practical applications.

Many people do not realize that the Internet that we know today is only possible because of technological developments that occurred in optical communication systems at the turn of the century. Today the Internet is an optical network of massive scale extending worldwide from individual homes to individual servers in mega-datacenters.  In fact it has grown to the point that our ability to continue to scale these technologies
