[Invited Paper] Enhanced Recording Density via Multilevel Phase Retrieval and Correlation-based Multiplexed Recording in Computer-generated Holographic Data Storage

Cavity enhanced image recording for holographic data storage

Previously, we proposed and experimentally demonstrated that optical cavities can be employed in recording and readout of plane wave holograms to improve data rates in Holographic Data Storage Systems (HDSS). However, there were some concerns about whether these techniques would be applicable to page based HDSS where signal beams are image bearing and have multiple wave vectors. We have consequ...

Localized Recording Approaches and Phase Metrology for Holographic Storage

The number of layers of a micro-holographic disk is limited by wavefront aberration which is strongly dependent on the photopolymer initiation, termination and inhibition kinetics. 3D metrology is used to validate predicted index profiles.

Dynamic Pattern Recognition and Data Storage Using Localized Holographic Recording

High-density recording in holographic data storage system by dual 2-level run-length-limited modulation

High-density recording in photopolymer-based holographic three-dimensional disks.

The performance specifications of a holographic three-dimensional disk system are experimentally characterized. A surface density of 10 bits/µm(2) is experimentally demonstrated with a 100-µm-thick photopolymer as the recording medium.
