摘要： A hybrid magnetic-optical head apparatus wherein one or more solid state lasers, magnetic field biasing elements, magnetic sensing elements, and an aerodynamically shaped slider comprise a single integrated, monolithic device fabricated from the same base semiconductor material into an optical head. The monolithic optical head can be quickly and easily attached to the read arm of an optical read/write device without requiring attachment of separate laser and magnetic elements, and without micropositioning or use of optical microscopy for positioning the lasers or magnetic elements. The hybrid magnetic-optical head apparatus includes a magnetic-optical function region having a semiconductor laser and at least one magnetic element. Preferably, the magnetic-optical function region of the substrate includes a magnetic field biasing element associated with the semiconductor laser, as well as a magnetic sensing element. The slider portion of the magnetic optical head preferably includes an aerodynamically shaped air cavity as well as an air bearing surface, with the emission face of the laser preferably is substantially co-planar with the air bearing surface. The magneticoptical function region may be configured for magnetically assisted thermal recording wherein writing is carried out primarily by laser power modulation to selectively heat portions of a medium, together with assistance of an applied magnetic field to establish a preferred direction of magnetization pattern in the medium. The magnetic-optical function region may alternatively be configured for thermally assisted magnetic writing wherein writing is carried out primarily by modulation of magnetic field, together with assistance of a laser which heats the medium to reduce the medium coercivity and thereby assist in the magnetic recording.

摘要： Digital data bits are stored at storage locations at plural depths within a holographic medium of a holographic storage disk in the form of selective, localized alterations in a format hologram. Micro-localized regions of a reflection format hologram extending throughout the medium are deleted by focusing a high-power laser beam at desired storage locations. The deletion regions have a lower reflectivity than the surrounding parts of the format hologram. Tunable-focus storage and retrieval heads, as well as dynamic aberration compensators, are used for multi-depth access. Storage and retrieval may each be achieved with a single head.

摘要： A near-field laser and detector apparatus and method wherein both writing and reading of optical media can be carried out using the same laser operating in a single mode for both read and write operations. The single operational mode can be utilized with both edge emitting and surface emitting laser configurations, and allows readout via rear facet output power variation or by voltage variation across the laser. A small aperture laser is operated during read and write operations at a bias current which is higher than the threshold currents associated with feedback from high and low reflectivity regions of an optical medium. The bias current and laser structure provide a relatively high, continuous output power from the front emission facet of the laser to facilitate writing, while providing substantial fluctuation or change in output power from the rear emission facet to facilitate readout.

摘要： A holographic data storage apparatus having no readout lens. The apparatus has a spatial light modulator (SLM), a focusing element such as a lens, a holographic data storage material and a spatial light detector such as a CCD. The lens is located between the SLM and CCD such that the SLM is imaged onto the CCD (i.e. the positions of the SLM, lens, and CCD satisfy the lens equation). The holographic storage material is located between the lens and CCD. Preferably, the storage material is located centered upon a Fourier plane of the lens. In this case, the apparatus also has a phase mask located adjacent to the SLM. Alternatively, the storage material is located a distance away from the Fourier plane or is not centered on the Fourier plane. In yet another embodiment, the holographic storage material is located in contact with the CCD.

摘要： A hologram with a dynamically controlled diffraction efficiency and enhanced signal-to-noise ratio is recorded in ferroelectric photorefractive materials, such as strontium barium niobate (Sr.sub.x Ba.sub.1-x Nb.sub.2 O.sub.6) (SBN), BSTN, SCNN, PBN, BSKNN, BaTiO.sub.3, LiNbO.sub.3, KNbO.sub.3, KTN, PLZT and the tungsten bronze family. The diffraction efficiency of the hologram is dynamically controlled by applying an electric field along the polar axis of the ferroelectric photorefractive recording medium. Electrically controlled diffraction is used in conjunction with hologram fixing and operation of the material at a temperature in the vicinity of or above its Curie temperature to additionally provide prolonged, low-noise readout. The general methods for recording and reconstructing a hologram (or a set of multiplexed holograms) using these techniques is disclosed. A plurality of configurations employing the improved hologram are disclosed, including an optical crossbar switch in guided-wave and free-space formats that can function as a component in a variety of parallel optical processing systems, a reconfigurable dynamic wavelength filter, and a page-based holographic data storage system.

摘要： Rare earth doped ferroelectric materials are disclosed as reversible holographic recording medium (25) for use in two-photon recording systems. Such rare earth elements provide long-lived electronic states intermediate the ferroelectric material's valence and conduction bands. In some cases, these rare earth intermediate states have a sufficiently long life that low-power continuous wave ("cw") lasers (1) can be used to record interference patterns on them. Thus, two-photon holographic recording systems are also disclosed which do not require high-power, short pulse length, mode-locked or Q-switched lasers. Rather, the disclosed holographic recording systems employ cw lasers such as diode lasers. The rare earth dopants include praseodymium, neodymium, dysprosium, holmium, erbium, and thulium. These dopants provide ions having 4f excited states that give rise to absorptions in the near infra-red and visible spectral regions and typically have lifetimes on the order of 0.1 to 1 milliseconds.The disclosed two-photon holographic recording systems provide for absoption of a first photon which excites electrons of a holographic recording medium to a rare-earth intermediate state. Thereafter, upon absorption of a second photon, the electrons are promoted to the medium's conduction band where they are arranged according to the interference pattern provided by the recording system.
