Secure Ultrafast Data Communication and Processing

Osamu Matoba and Bahram Javidi

Ultrafast data communication and processing systems that use ultrashort pulses allow data transfer rates faster than 1 Tbit/s without conversion to electronic signals. Spatiotemporal converters based on spectral holography are a key to the successful implementation of such systems. To send large amounts of data at ultrafast transfer rates, high-capacity data-storage systems that can operate at equally high rates of speed are also required. Holographic memo-ries can serve as an interface in ultrafast data communication, while optical encryption techniques can be used to ensure the security of the transmitted data.
