Bio-X Affiliated Faculty

Dr. Kahn's research addresses communication and imaging through optical fibers, including modulation, detection, signal processing and spatial multiplexing.

The Optical Communications Group applies principles of photonics, signal processing, communications and information theory to advance the performance of communication or imaging systems. They have demonstrated sustained technical leadership in several optical communication media, including single-mode fiber (SMF), multi-mode fiber (MMF), and free-space optical (FSO) links, setting world records for speed and efficiency in each medium. They have also made seminal, highly cited contributions to multi-input, multi-output (MIMO) wireless communications and sensor networks.
