Abstract: Highly discriminating optical edge filters and methods of making the same are disclosed. The optical edge filters have an edge steepness greater than about 0.8% as measured by dividing (a) the edge width from the 50% transmission wavelength to the optical density 6 (“OD6”) wavelength by (b) the 50% transmission wavelength. The optical filters also have an average transmission above about 95%. The methods for making such filters accurately determine when deposition of each layer of the filter should terminate. The methods include calculating theoretical transmission data for a layer of the filter and calculating an expected deposition duration for the layer. The methods also include measuring transmission through the layer during deposition for a period less than the expected deposition duration. When the measuring period elapses, a new deposition duration is calculated based upon the theoretical transmission data and the measured transmission data, thereby providing an accurate deposition duration for the layer.

Abstract: A single-mode fiber includes a grating located near a fiber tip to shift transmitted light from a fundamental core mode to one or more higher cladding modes. Light exiting the fiber from the cladding mode occupies more area but is more collimated. Translational alignment tolerances are relaxed by the improvement in collimation, allowing couplings to be made directly with the single-mode fiber or through the intermediacy of a conventional lens, which can itself be aligned more readily and be less fast.

Abstract: An optical transmission system having a transmission waveguide, an optical amplifier, a pump radiation source for supplying pump radiation to the optical amplifier, and a Bragg grating for reflecting pump radiation to the amplifier. The Bragg grating is produced using two collimated, non-collinear beams of actinic radiation to form an interference pattern in a medium. While changing the product .lambda..times.0.5 csc .phi./2, the interference pattern is advanced relative to the medium such that the interference pattern has a spatially varying period. The resulting Bragg grating has a sufficiently wide bandwidth in reflection, sufficiently high extinction in transmission, and sufficiently low intrinsic loss that the pump radiation source may be located at least one kilometer from the optical amplifier.

Abstract: The invention involves a method for making Bragg gratings in glass optical fibers, or other glass optical waveguides, which is relatively insensitive to perturbations in the actinic light used for processing. This method is suitable for mass production and lends itself well to the manufacturing environment. The invention method involves first providing an optical phase grating. An interference pattern is generated by impinging a single light beam on the grating. The optical waveguide to be processed is exposed to this interference pattern, leading to the formation of a Bragg grating in the waveguide.
