摘要： The present invention relates to a method for servo writing an optical or magneto-optical medium where a data path is defined by transmitting a laser beam onto the medium to change the crystalline structure at preselected portions. These portions can guide an optical head along the data path. Embodiments include using a far-field laser servo writer to transmit a laser beam in combination with a high numerical aperture, using a far-field laser servo writer to transmit a laser beam in combination with a solid immersion lens, using a near-field laser servo writer to emit a laser beam in combination with a solid immersion lens, creating a sub-wavelength aperture for emitting a laser beam onto the medium, lithographic and maskless lithographic techniques. The present invention also relates to a medium for the storage of data which has portions of its substrate with a different crystalline structure than the rest of the substrate of the medium, so that these portions of the substrate can serve as optically created servo fields for a tracking device.

摘要： Using simple optical components and an unmodified commercial off-the-shelf semiconductor laser, a frequency-selective self-aligning optical-feedback technique has been devised that allows a semiconductor laser to be tuned to and scanned about any optical frequency within the laser gain curve. This technique employs a graded-index rod lens cat's eye and an intracavity etalon for selecting one laser side mode. By changing the external cavity length, the laser frequency can be continuously tuned within one external cavity free spectral range. To further extend the tuning range, the laser injection current is changed to produce a discontinuous hop in the laser frequency. To eliminate the hops the cavity length and laser current are changed simultaneously.

摘要： An optical non-contact profilometry system and method provided by an optical caliper with matched optical sensors that are arranged conjugate to each other so that the surface profile and thickness of an article can be measured without using a fixed reference surface and while permitting the article to deflect in space within the acquisition range of the optical sensors. The output signals from the two optical sensors are algebraically added to compensate for any such deflection of the article and provide a so compensated signal, the balance and sign of which provides a measurement of the actual thickness of the article at the optical sensors.

摘要： A method for making a high-power fused collimator, and a fused collimator made thereby, are provided. A fused collimator is provided that includes an end of a stripped end portion of an optical fiber fused to a proximal face of a silica lens. In an embodiment, a joint formed by the fiber end and the silica lens proximal face is substantially surrounded with a solder glass in a melted form. A cross-sectional area of the solder glass decreases proximally from a distal edge adjacent the lens to a proximal edge located along the fiber's stripped end portion. The solder glass is permitted to harden, forming a fused collimator. In another embodiment, a ferrule surrounds the fiber stripped end portion, and an adhesive is applied to the ferrule's proximal face to surround the fiber. The lens-ferrule joint is surrounded with solder glass, which is then surrounded with a silica sleeve.

摘要： Differential polarization imaging systems include an axicon configured to provide a displacement of ray bundles associated with different image patches. The displaced ray bundles are directed to antenna horns and orthomode transducers so as to provide outputs correspond to orthogonal linear states of polarization (SOPs). The outputs are directed to a differential radiometer so that Stokes parameter differences between image patches can be obtained. The ray bundle displacements can be selected to correspond to a mechanical spacing of antenna horns. In some examples, ray bundle displacement corresponds to a displacement less than the diffraction limit.
