摘要： Methods, devices, systems, and materials are disclosed for diffraction unlimited photofabrication. A method is provided where a photoresponsive material is illuminated with a first optical pattern at a first wavelength of light. The first wavelength of light alters a solubility of the photoresponsive organic material. The photoresponsive material is also illuminated with a second optical pattern at a second wavelength of light. The second wavelength of light hinders the ability of the first wavelength of light to alter the solubility of the photoresponsive organic material where the second optical pattern overlaps the first optical pattern. The photoresponsive organic material is then developed.

摘要： Conventional retroreflection mirrors in the form of right angle prisms are quite sensitive to beam position and beam angle errors. Manufacturing and assembly tolerances are also a cause of concern in conventional devices. Accordingly, the present invention solves these aforementioned problems by providing a retroreflection device comprising: a beam director, preferably in the form of a Wollaston prism; a polarization rotator, preferably in the form of a quarter wave plate; and a flat reflective surface, such as a plane mirror. The device of the present invention is far less sensitive to beam angle alignment and is completely independent of the beam position. The present invention is particularly useful as a beam splitter for directing orthogonally polarized beams of light back along parallel paths in an interleaver apparatus.

摘要： An improved focus error signal generator device including two optical lenses in series; a birefringent optical lens followed by a standard optical lens, the lenses being disposed in the path of a return read beam wherein the birefringent optical lens has a first and second focal plane. A pinhole is disposed in the path of the return read beam in close proximity to the first and second focal planes. A polarizing beam splitter is positioned after the second focal plane and serves to split the return read beam into two light beams of polarization associated with the first and second focal planes. First and second detectors are positioned so as to read the two light beams signals output from the polarizing beam splitter and the detectors are connected to an electrical differencing circuit having an output to an optical head servo system.

摘要： The frequency-sampling method is widely used to accommodate nonlinear electromagnetic source tuning in swept-wavelength interferometric techniques, such as optical frequency domain reflectometry (OFDR) and swept-wavelength optical coherence tomography (OCT). Two sources of sampling errors are associated with the frequency-sampling method. One source of error is the limit of an underlying approximation for long interferometer path mismatches and fast electromagnetic source tuning rates. A second source of error is transmission delays in data acquisition hardware. Aspects of the invention relate to a method and system for correcting sampling errors in swept-wavelength interferometry systems such that the two error sources correct sampling errors associated with the first radiation path and the second radiation path cancel to second order.

摘要： A tracking error signal generation apparatus and method which utilizes confocal detection with a split detector and a differencing circuit for generation of tracking error signals. A first lens is positioned in the path of a light beam returning from an optical medium. A pinhole is positioned in the path of the light beam after the first lens and proximate to the focal plane of the first lens. A second lens is positioned in the path of the light beam after the pinhole, and a split detector, having equal halves is positioned in the path of the light beam after the second lens. A differencing circuit is operatively coupled to each of the halves of the split detector. In operation, a light beam is focused by an optical head onto a track in the optical medium, and the reflection of the beam from the optical medium is directed through the first lens, through the pinhole, through the second lens, and onto the split detector. When the focus of the light beam is centered on the track, the reflected light reaching the split detector is evenly distributed on the two halves of the detector, such that the differencing circuit will generate a tracking error signal (TES) having nominally a zero value. When the focus of the light beam is off-center with respect to the track, the reflected light received by detector is unevenly distributed on the two halves of the detector such that the differencing circuit generates a non-zero tracking error signal, which will be of positive or negative value depending upon the direction off-center of the light beam focus spot. The tracking error signals thus generated are communicated to a servo system which will reposition the optical head to maintain the light beam focus spot on the center of the track.

摘要： The invention provides an optical system for use in a stable, temperature-insensitive birefringent crystal interferometer (BCI). The optical system includes a first block of light transmissive birefringent material having an input port and an output port, the material having in the spectral region of desired device operation a net retardance at a first temperature, and straining means for inducing a strain in one of the first block and a second block of light transmissive material optically coupled to the first block, the strain induced for maintaining the net retardance substantially unchanged from the net retardance at least a second other temperature. Advantageously, the optical system uses a single variety of crystal, which is cheaper, more robust, and has better performance than BCIs having two crystal varieties.
