摘要： An apparatus and method for optical data storage and/or retrieval using an optical data storage medium having a spatially-modulated refractive index that can be altered locally with optical methods. Data can be written at a plurality of depths throughout the volume of the medium using a write beam and relatively simple and inexpensive optical components. The write beam stores data locally by physical distortion of the medium at discrete storage locations. The alterations can be detected as variations in the reflectivity of the storage locations using a retrieval beam.

摘要： An optical data storage system and method comprising a photopolymer medium having generally a polymerizable monomer, an active binder, a first, hologram recording polymerization initiator, and a second, data writing polymerization initiator. The monomer is preferably a cationic ring-opening monomer. The hologram recording polymerization initiator preferably comprises a sensitizer and photoacid generator which initiate a first polymerization in the medium which defines a format hologram. The format hologram recording is carried out via interference of a signal and reference beam, with the sensitizer being specific for the wavelength(s) of the signal and reference beams. The hologram recording polymerization is only partial and does not consume all of the monomer present in the photopolymer medium. A second stage, a data writing polymerization initiator, specific to a data writing beam, locally advances polymerization at selected data storage locations to alter the previously recorded format hologram, resulting in optical data storage as localized alterations in the format hologram.

摘要： Alignment of a laser apparatus is achieved by actively aligning components of the laser apparatus and then passively deriving an optical axis from that alignment. This passive derivation can be achieved by identifying features of an actively aligned optical element, deriving positional data for those features, and developing an optical axis from that positional data. The derivation of positional data may be performed over a particular coordinate system of an image taken of the feature, e.g., obtained by a vision system. The positional data and optical axis may be extrapolated out to a reference coordinate system for use in passively aligning other optical elements.

摘要： Semi-integrated external cavity diode laser (ECDL) designs including integrated structures comprising a gain section, modulator section, and optional phase control section. Each integrated structure includes a waveguide that passes through each of the sections, with the waveguide further including an in-waveguide mirror. The in-waveguide mirror defines one end of an “effective” laser cavity, with the other end defined by a reflective element disposed generally opposite a rear facet of the integrated structure, forming an external cavity therebetween. The in-waveguide mirror is formed by using a focused ion beam (FIB) cut through the waveguide, or by etching one or more trenches through the waveguide and backfilling the trenches using a re-grown crystal or amorphous material deposition process. A tunable filter is disposed in the external cavity to effectuate tuning of the laser. The modulation section of the integrated structure enables high-speed modulation of an optical signal at a selected communication channel without requiring an external modulator.

摘要： Semi-integrated external cavity diode laser (ECDL) designs including integrated structures comprising a gain section, phase control section, and optional modulator section. Each integrated structure includes a waveguide that passes through each of the sections. A mirror is defined in the structure to define one end of a laser cavity. A reflective element is disposed generally opposite a rear facet of the gain section, forming an external cavity therebetween. A tunable filter is disposed in the external cavity to effectuate tuning of the laser. During operation, a modulated drive signal is provided to the phase control section. This modulates an optical path length of the laser cavity, which produces an intensity (amplitude) modulation in the laser output. A detector is employed to produce a feedback signal indicative of the intensity modulation that is used for tuning the laser in accordance with a wavelength locking servo loop. Upon passing through the modulator section, an optical signal is modulated with data.
