26 August 2015 Potential of multi-photon reading and writing for optical data storage systems
Author Affiliations +
Multi-photon (MP) optical data storage systems (ODS) have been discussed for many years. A differentiating advantage for MP systems is the ability to interrogate through the depth of a multiple-layer substrate without significant influence from out-of-focus layers. Until recently, these systems have been impractical due to the cost, size and complexity of the lasers used for writing and reading. This presentation discusses a brief overview of MP physics for ODS, writing and readout techniques, MP-ODS systems published to date, potential storage densities, new compact MP laser sources appropriate for ODS, and a new MP enhancement effect for readout signal enhancement.
