Satellite Laser Communications
This course will provide an introduction and overview of laser communication principles and technologies for unguided, free-space beam propagation. Special emphasis is placed on highlighting the differences, as well as similarities to RF communications and other laser systems, and design issues and options relevant to future laser communication terminals.
Dr. Hamid Hemmati, Ph.D. has just joined Facebook Inc. as Director of Engineering for Telecom Infrastructure. Until May 2014 he was with the Jet Propulsion Laboratory (JPL), California Institute of Technology where as Principal member of staff and the Supervisor of the Optical Communications Group. Prior to joining JPL in 1986, he was a researcher at NASA’s Goddard Space Flight Center and at NIST (Boulder, CO). Dr. Hemmati has published over 200 journal and conference papers, nine patents granted and two pending. He is the editor and author of two books: “Deep Space Optical Communications” and “Near-Earth Laser Communications” and author of five other book chapters. In 2011 he received NASA’s Exceptional Service Medal. He has also received 3 NASA Space Act Board Awards, and 36 NASA certificates of appreciation. He is a Fellow member of OSA (Optical Society of America) and the SPIE (Society of Optical Engineers). Dr. Hemmati’s current research interests are in developing laser communications technologies and low complexity, compact flight electro-optical systems for both inter-planetary and satellite communications and science. Research activities include: managing the development of a flight lasercom terminal for planetary applications, called DOT (Deep-space Optical Terminals), electro-optical systems engineering, solid- state lasers (particularly pulsed fiber lasers), flight qualification of optical and electro- optical systems and components; low-cost multi-meter diameter optical ground receiver telescopes; active and adaptive optics; and laser beam acquisition, tracking and pointing.
