Holographic optical storage nears commercialization

July 10, 2015
A collaboration is developing and producing what it says is the next generation of nanophotonic data storage (N-PDS) technologies.

Access Optical Networks (AON; Manalapan, NJ), in collaboration with Princeton University (Princeton, NJ) and the California Institute of Technology (Caltech; Pasadena, CA), is developing and producing what it says is the next generation of nanophotonic data storage (N-PDS) technologies. This holographic N-PDS platform, which Laser Focus World first reported on in early 2012, uses lasers that read, rewrite, and transfer data bits stored in volumetric photorefractive crystals. The memory product's development is on track to reach its 1.2 Tbyte data storage density with 1 Gbit/s read and rewrite performance—with significant benefits over blue laser and Tapestry holographic storage media from Akonia Holographics (Longmont, CO), who acquired InPhase Technologies.

AON is making substantial progress on a $20 million funding round, with commitments from private equity groups and strategic partners for half of the funds raised and plans to close on the final balance of funding by August 2015. The funds will allow commercialization of its N-PDS technology during the next 30 months. Currently, AON's N-PDS technology is the only nonvolatile optical data storage device that can be clean-erased in minutes with no residual data that would enable forensic recovery—important for high-performance computing and cyber-security systems. The technology also supports data tagging using phase coding and/or polarization coding, and enables optical search techniques such as facial recognition and geospatial applications—including urban and rural topographic extraction and pattern matching.
