| 20100321748 | METHOD AND SYSTEM FOR RE-WRITING WITH A HOLOGRAPHIC STORAGE MEDIUM - A method and device for re-writing data on a holographic storage device is disclosed. First and second electro-optic modulators may phase shift the reference and data beams used to store data on the photorefractive crystal. When the reference beam is shifted 180° out of phase with respect to the data beam, the photorefractive crystal is erased. | 12-23-2010 |
| 20100321749 | METHOD AND APPARATUS FOR BULK ERASURE IN A HOLOGRAPHIC STORAGE SYSTEM - A method and system for bulk erasing in a holographic storage system is disclosed. The method may involve illuminating the entire volume storage region of a photorefractive crystal with a laser to achieve bulk erasure, or may involve selective erasure of a portion of a single written page. For bulk erasure of the entire photorefractive crystal the use of a separate laser or an incoherent light source is used. | 12-23-2010 |
| 20100321759 | DIRECTLY MODULATED SPATIAL LIGHT MODULATOR - A directly modulated spatial light modulator (DM-SLM) may be formed using a semiconductor optical amplifier. The directly modulated spatial light modulator may also be formed with a vertical cavity surface emitting laser having an output side; and an anti-reflection coating located on the output side. | 12-23-2010 |
| 20100322058 | HOLOGRAPHIC STORAGE SYSTEM USING ANGLE-MULTIPLEXING - A holographic memory storage device that uses a photorefractive crystal for storing data is disclosed. The device uses angle-multiplexing in order to store and retrieve page data and sub page data. MEMS devices are used in order to provide individual sector addressing. | 12-23-2010 |
| 20100322553 | OPTICAL SENSOR ARRAY - A switching array is disclosed that has a plurality of vertical cavity surface emitting lasers having phase shifting mirrors. The switching array may be used for providing a device and system that has optical signal processing of sensing, a serialization and protocol interface, that has increased gray scale levels and sensitivities, pixel polarization detection, higher speed, lower power requirements and provides optical or electrical output for holographic optical storage to a bus or network. | 12-23-2010 |
| 20100325513 | INTEGRATED CONTROL ELECTRONICS (ICE) FOR A HOLOGRAPHIC STORAGE SYSTEM - Integrated control electronics for a holographic storage system that is adapted for controlling read/write logic in a holographic storage device. The control electronics may control beam steering devices, SLM devices, shutters, optical sensor arrays and lasers. | 12-23-2010 |
