摘要： All-optical logic gates in which binary words are encoded using wavelength. A method and apparatus for processing information in this wavelength encoded format is provided. The processing may occur entirely in the optical domain. This approach is modular and enables construction of logic gates using custom waveguide chips that can be mass-produced in a manner similar to that of conventional electronic digital chips. Specific gates, such as AND, OR, EXOR, or NAND, may be "programmed" into a given chip during its fabrication to encode the desired truth table. The ouptut states of the chip are determined by ultrafast mixing of binary encoded wavelengths in a semiconductor optical amplifier. The result is a new wavelength having a relationship to the input wavelengths determined entirely by the desired truth table.
