摘要： A method for dynamically refreshing a holographic data storage medium wherein data is stored in a plurality of data pages, each of which comprises a two dimensional pattern of pixel data. Each data page is stored by interfacing an image or a Fourier transform of the data page with a reference beam to form a holographic recording of the data page in the holographic medium. Pursuant to the method, all of the data pages are classified as either good pages, each of which was written into storage less than a threshold time ago related to the decay of the holographic recording, or empty pages available for writing, or self-erasing pages which are self-erasing with time. At sequential time intervals, the oldest good page is read which then becomes a self-erasing page, and its data is rewritten into an empty page which then becomes the youngest good page, and the oldest self-erasing page becomes an empty page.

摘要： A compound semiconductor that is suitably doped to exhibit the DX effect is irradiated with an optical beam of spatially varying intensity whereby localized regions of persistently higher conductivity and lower refractive index are created in the semiconductor where sufficient intensity of the beam was incident. The persistently higher conductive region can be used to bridge selected gaps in conductive paths on a support member use in memory device and the regions of lower refractive index can be used to providing guiding in a wave guide, to form high resolution gratings, or to form holograms.

摘要： An information processing system uses a planar optical waveguide as a shared medium for a plurality of its subsystems. To this end, each subsystem is provided with a light emitting diode to broadcast information pulses into the shared medium and a photodetector for receiving the information pulses broadcast by the light emitting diodes. This thereby reduces the need for conductive interconnections between subsystems. Additionally, a number of planar optical waveguides can be stacked on a support and different compositions of subsystems communicate with one another by using different waveguides of the stack. The system can be adapted for time-division, space-division and frequency division multiplexing.

摘要： Full duplex operation is achieved in a lightwave communication system by employing terminals having a distributed Bragg reflector (DBR) laser having separate electrically controllable Bragg reflector and gain sections. While operating as the basic heterodyne reception element, the DBR laser simultaneously generates lightwave signals for transmission to other terminals. External circuits process the electrical (intermediate frequency) signals from the simultaneously modulated and signal mixing laser to extract received information. In one embodiment, full duplex operation is described for an FSK lightwave communication system.

摘要： A read/write head for an optical storage medium is provided. The read/write head comprises a waveguide having an end face and a plasmon-enhanced device provided on the end face of the waveguide. The plasmon-enhanced device comprises a metal film having a first surface and a second surface, the first surface being fixed to the waveguide end face, the metal film having an aperture provided therethrough. The metal film has a periodic surface topography provided on at least one of the first and second surfaces of the metal film. Light incident on one of the surfaces of the metal film interacts with a surface plasmon mode on at least one of the surfaces of the metal film thereby enhancing transmission of light through the aperture in the metal film which is directed onto and/or collected from the optical storage medium. A read/write head with an integral light source is also provided. The invention also provides an array of precisely aligned read/write heads, and an array of precisely aligned read/write heads with integral light sources, as well as side-emitting lasers and vertical cavity surface emitting lasers (VCSELs) with enhanced transmission.

摘要： A semiconductor laser with a rewritable wavelength stabilizer which comprises a laser mirror made of a grating written into a photorefractive material, in which the oscillation wavelength of the laser diode is determined by the period of the grating. This allows the refractive index of the grating to be changed by illuminating the photorefractive material after cooling thereof to a temperature at which most of the doped impurities form DX centers. The grating can be erased by heating the photorefractive material to a temperature at which most DX centers are ionized, which erases the grating. Thereafter the photorefractive material is cooled again to a temperature at which most impurities become DX centers, and a new grating can be written in the photorefractive material. The wavelength of the semiconductor laser can be changed repeatedly by erasing and rewriting the grating therein. The laser diode is maintained and operated at a low temperature to maintain the grating semi-permanently therein while the temperature remains low.
