Free-Space optical communication for sensor networks and secure data links
Prof. Joseph M. Kahn
EE, Stanford University

This talk will provide a brief overview of my group's research activities in optical fiber communications and free-space optical communications. Our recent efforts in free-space optical systems will be emphasized, including:

  • Free-space optical communication for "smart dust" motes. These are autonomous nodes incorporating sensing, data storage, power source and wireless transceiver in a volume of just a few cubic millimeters.

  • Secure, short-range free-space links between airplanes and other rapidly moving vehicles.

  • Spatial- and temporal-domain communication techniques to mitigate turbulence effects in free-space optical links.
