Hybrid sparse-wavelength angle-multiplexed optical data storage system

We propose, analyze, and demonstrate a hybrid wavelength-and-angle-multiplexed optical data storage system. Our system utilizes multiwavelength information processing in conjunction with angle-multiplexed volume holographic storage, achieving direct compatibility with wavelength-encoded optical logic processors. Such a scheme also allows for rapid recall of high-density data into electronic processing and display systems. Hybridization of wavelength and angle multiplexing relaxes demands on spectral and angle-tuning sources and allows for the use of present-day-available optical sources and components.
