Aref Chowdhury,[1] who joined Bell Labs in 2001, specializes in nonlinear optics and biochemical detection research. His work in nonlinear optics, a field critical to improving long-haul optical transport networks, focuses on minimizing distortions due to nonlinear effects in optical signals. Using a technique called optical phase conjugation, Chowdhury and his colleagues are able to correct errors in optical communications by reversing the distortions that occur over time, as signals speed through the network. This work has the potential[according to whom?] to increase the efficiency and reliability of optical communications.
