Abstract
OCDMA systems provide for storage and retrieval of OCDMA data while maintaining OCDMA encoding. One system includes an optical splitter that receives an OCDMA data stream having a multiple wavelengths of light. A plurality of tunable light filters is optically interconnected with the optical splitter. A controller tunes the tunable light filters such that they switch wavelengths of the OCDMA data stream over time. A plurality of light detectors is respectively coupled to the tunable light filters to convert the filtered optical data streams from the tunable light filters to electronic data streams. Each generated electronic data stream is stored with a corresponding storage volume. Retrieval of the OCDMA data is performed by reversing the wavelength switching used to store the OCDMA data stream. The electronic data streams are thereby converted to optical data streams using tunable light generators and subsequently converted into the OCDMA data stream with an optical coupler.
