Optical code division multiple access data storage and retrieval

摘要

An OCDMA system is disclosed that provides for storage and retrieval of OCDMA data while maintaining OCDMA encoding and signaling information. The system includes a wavelength demultiplexer that optically receives an OCDMA signal having a plurality of wavelengths of light. A plurality of light detectors is optically interconnected with the wavelength demultiplexer, with each of the light detectors being associated with a unique wavelength of light. Each of the light detectors respectively communicates with a plurality of storage volumes. For example, each storage volume is associated with a unique wavelength of light and is configured for storing optical data electronically converted from an optical data stream having a unique wavelength of light. Such a process may substantially eliminate the need for OCDMA conversion during electronic storage of the OCDMA data. Stored OCDMA data may be rapidly retrieved and configured as an OCDMA signal because OCDMA coding is maintained.
