摘要： A compact optical isolator includes a polarizer, a Faraday rotator, and an analyzer that are arranged in series. A magnet is also included to provide a magnetic field to the Faraday rotator. The outer edges of the polarizer, Faraday rotator, and analyzer are preferably parallel to each other and to the optical path of the incoming light beam so that the optical aperture through the optical isolator is maximized. In addition, each of the polarizer, the Faraday rotator, and the analyzer have at least one facet in the optical path of the light beam that is tilted from perpendicular with respect to the light beam such that reflections are avoided. The analyzer may have a wedge shape such that one surface mates level with an optical fiber and the opposing surface is tilted to prevent reflections. Alternatively, a wedge-shaped block may be located between the analyzer and the optical fiber.

摘要： An interleaver device and associated methods of manufacturing and calibration that use a laser bending technique to adjust the relative position of interferometers of the interleaver. The interleaver device includes a laterally divided housing with two lateral portions separated by supports. The supports are web like structures, the length of which can be adjusted in a predictable or measurable manner in response to a laser beam. The laser bending calibration and manufacturing technique uses a laser and a feedback and control system to adjust the spacing and angular relation between the lateral portions by partially melting one or more of the supports. The feedback and control system includes an optical detector, a computer, and a positioning system. This combination of components allows the interleaver device to be calibrated to precisely adjust the separation between channels within a WDM optical signal.

摘要： A method for digital phase detection, comprises the steps of: providing a reference clock; receiving a feedback clock; determining a timing difference between the reference clock and the feedback clock; determining a polarity that indicates the leading or lagging relationship between the reference clock and the feedback clock; adaptively selecting one of at least two operating modes for generating a quantized level indicative of the timing difference, wherein in a first operating mode the quantized level is a constant maximum value and wherein in a second operating mode the quantized level is proportional to the timing difference; and generating a digital phase detection output as a combination of the polarity and the quantized level.
