Abstract :
Summary form only given. Ultra-fast byte-wide data transmission between high-speed computers can be achieved using a spectral data bus where each bit is assigned a different wavelength and data is transmitted on one optical fiber. All-optical signal processing for header recognition, routing, error correction or encryption can improve the throughput of a cluster of linked computers. All-optical logic operations on PolSK (polarization shift key) coded data using FWM (four-wave mixing) in SOAs (semiconductor optical amplifiers) which exploit the polarization properties of the nonlinearity have been proposed and demonstrated. Furthermore, FWM on PolSK coded bits can be used to construct higher-level logic elements to implement truth tables involving several WDM (wavelength division multiplexed) data bits without resorting to elemental Boolean functions such as NAND/NOR. We demonstrate all-optical EC (error-correction) on a (3,1) Hamming code.
