摘要： A system (10) for detecting a small fiber loss (102) on a fiber (104) includes a first channel (106) having a first wavelength coupled to the fiber (104). A second channel (108) having a second wavelength different than the first wavelength is also coupled to the fiber (104). At least one photodetector circuitry (110) is coupled to the fiber (104) at a monitor point (112) for detecting a change in the power ratio between the first and second channels for detecting the small fiber communication loss (102) at any location along the fiber (104).

摘要： The invention provides a cable having a core comprising at least one transmission element (3) selected from the group consisting of optical fibers, electric conductors and tensile elements. A jacket (11) comprising polymeric material encloses the core, and at least one monitoring optical fiber (12) is embedded within said jacket. The jacket (11) is sufficiently opaque for said monitoring optical fiber (12) to be substantially invisible to an observer looking at the outside of the jacket (11). In use, a source of optical signal is coupled to one end of the monitoring fiber (12) and a detector for the optical signal is coupled to the other end of said fiber. The detector thus gives warning of damage; for example, an attempt to eavesdrop on a signal being transmitted by optical fibers in the core of the cable may be detected in time for the transmission of sensitive information to be stopped and the attempt foiled.

摘要： Disclosed is a method of making a photonic crystal preform which provides improved properties of the photonic band-gap crystal waveguide fiber drawn therefrom. The photonic crystal preform defect is formed using materials having a particular shape or composition so that the defect walls are preferentially etched away to provide a photonic band-gap crystal waveguide fiber having a smooth walled defect.

摘要： Microlens array are defined by with microlens (10) elements that differ from each other in accordance with a probability distribution function for shaping an optical beam having a prescribed intensity profile within a desired far-field scatter pattern. The differences include random variations in sag profile corresponding to a surface shape (60) of the micro lenses, a boundary profile (46) corresponding to a boundary of the micro lenses, and a spatial distribution corresponding to the relative position of the micro lenses within the array. The sag profile variations can be used to homogenize an intensity profile of the optical beam. The boundary profile variations within an irregular spatial distribution can be used to apply the prescribed intensity profile of the optical beam within the desired scatter pattern.

摘要： Flatness and thickness variation information concerning transmissive plane-parallel test plates (12) is obtained from a grazing incidence interferometer (10) modified to distinguish between interference patterns containing both types of information. The grazing angle of the interferometer is varied (30, 32), and unique modulation frequencies of local fringe intensities within the superimposed interference patterns are identified. The local fringe intensities attributable to the different interference patterns are distinguished by their respective modulation frequencies.
