摘要： An all-optical cross-connect switching system provides optical switching that may reduce processing requirements by three orders of magnitude over conventional techniques by associating at least one optical detector with an optical beam steering element. In one embodiment, a first beam steering element, having a reflective surface in optical association with a first optical fiber array, and a second beam steering element, having a reflective surface in optical association with a second optical fiber array, are optically arranged to direct an optical beam from a first optical fiber in the first optical fiber array to a second optical fiber in the second optical fiber array. The optical detector provides information about a first position of the optical beam on the second beam steering element. Based on this information, the angle of the first beam steering element may be adjusted to cause the optical beam to change to a second position on the second beam steering element.

One apparatus includes an optical source coupled to provide an optical signal in response to a DC bias and an AC bias corresponding to a pilot tone signal. A processor is coupled to compute each of an AC component and a DC component of the optical signal from the same digitally sampled signal. A feedback control is coupled to vary at least one of the DC bias and the AC bias in accordance with a difference between a pre-determined value and a ratio of the AC and DC components.

摘要： Methods and apparatus related to maintaining a pre-determined ratio of a pilot tone power and a total mean optical power of an optical signal are provided. One method includes the steps of detecting the AC and DC components of an optical signal having a pilot tone signal. An amplitude of the pilot tone signal is varied in accordance with a difference between a pre-determined value and a ratio of the AC and DC components. Another method includes the step of generating an optical signal in accordance with a DC bias and an AC bias corresponding to a pilot tone signal. The AC and DC components of the optical signal are detected. At least one of the DC bias and the AC bias is varied in accordance with a difference between a pre-determined value and a ratio of the AC and DC components. An apparatus includes an optical source providing an optical signal in response to a DC bias and an AC bias corresponding to a pilot tone signal. The apparatus includes detectors coupled to measure the AC and DC components of the optical signal. A feedback control varies at least one of the DC bias and the AC bias in accordance with a difference between a pre-determined value and a ratio of the AC and DC components. In various embodiments, the DC bias only, the AC bias only, or both the AC bias and the DC bias are varied.

摘要： Method of producing a silicon structure for fabricating integrated circuit devices therein by forming a plurality of regions of N-type single crystal silicon of high resistivity inset in the surface of silicon of either P-type conductivity or of N-type conductivity of low resistivity. The silicon contiguous with the regions of high resistivity N-type silicon is converted to porous silicon by anodically treating in an aqueous solution of HF. Then, conductivity type imparting material is diffused through the porous silicon into portions of the regions of N-type conductivity to alter their electrical characteristics to P-type or to low resistivity N-type. The porous silicon is then oxidized to silicon oxide, electrically isolating each of the N-type regions and its associated portion.
