Title: Apparatus and method for combining light from two or more fibers into a single fiber

Abstract

An apparatus and method for combining light signals carried on a plurality of input fibers onto a single receiving fiber with a high degree of efficiency. The apparatus broadly comprises the receiving fiber and a plurality of input fiber-lens assemblies, with each fiber lens assembly including an input fiber; a collimating lens interposed between the input fiber and the receiving fiber and adapted to collimate the light signal; and a focusing lens interposed between the collimating lens and the receiving fiber and adapted to focus the collimated light signal onto the face of the receiving fiber. The components of each fiber-lens assembly are oriented along an optic axis that is inclined relative to the receiving fiber, with the inclination angle depending at least in part on the input fiber's numerical aperture and the focal lengths and diameters of the collimating and focusing lenses.

  • Methods for the preparation of carbon fiber from polyolefin fiber precursor, wherein the polyolefin fiber precursor is partially sulfonated and then carbonized to produce carbon fiber. Methods for producing hollow carbon fibers, wherein the hollow core is circular- or complex-shaped, are also described. Methods for producing carbon fibers possessing a circular- or complex-shaped outer surface, which may be solid or hollow, are also described.
  • Diagnostic apparatus for use in determining the proper alignment of a plurality of laser beams onto a fiber optics interface is disclosed. The apparatus includes a lens assembly which serves two functions, first to focus a plurality of laser beams onto the fiber optics interface, and secondly to reflect and image the interface using scattered light to a monitor means. The monitor means permits indirect observation of the alignment or focusing of the laser beams onto the fiber optics interface.

  • This patent describes a diagnostic apparatus for use in the alignment of one or more beams onto a fiber optics interface. The diagnostic apparatus comprises: monitor means; lens assembly means for imaging one or more of laser beams passing through an aperture onto the fiber optics interface. The assembly means is slightly offset in an optical orientation from its center line optical axis. The lens assembly means includes at least one lens where the one lens includes reflection means on the rear surface of one lens such that when a minor scattering of laser beams are reflected from the interfacemore » back to the lens assembly means, the reflection means on one lens reflects, images and directs the scattered light toward the monitor means; the monitor means is optically oriented to permit monitoring of reflected light for indirect observation of the alignment of focused laser beams onto the fiber optics interface.« less
