摘要： A glass base material producing method produces a glass base material through fixing, deposition, pullout, consolidation, and collapse steps in sequence, while the fixing step inserts and fixes a starting bar 11 into a seed rod pipe 12 such that a leading end part 11a of the starting bar 11 projects from one end 12a of the seed rod pipe 12, thereby making a starting rod 10. The starting rod 10 made in the fixing step Si yields a level difference of at least 0.1 mm but not exceeding 0.5 mm at the one end 12a of the seed rod pipe 12. Fine glass particles are deposited on the seed rod pipe in the deposition step in an axial range of at least 50 mm from a position where the level difference exists.

摘要： A micro identification system supports facile optical assemblies and components. A segment of optical fiber can comprise an identifier formed via actinic radiation. The identifier can generate a laser interference pattern that can be read through a cylindrical surface of the optical fiber to determine a code. Modified optical fibers are those fibers that have been shaped or coated to an extent beyond the demands of normal communications optical fibers. In one example, modified fibers are no longer than about two feet in length. For another example, the modified fibers can have either a non-cylindrical end face, a non flat end face, an end face the plane of which is not perpendicular to the longitudinal axis of the waveguide, an end face coated with high density filter, or an identifier on or near an end face.

摘要： A deterministic methodology is provided for designing optical fibers that support field-flattened, ring-like higher order modes. The effective and group indices of its modes can be tuned by adjusting the widths of the guide's field-flattened layers or the average index of certain groups of layers. The approach outlined here provides a path to designing fibers that simultaneously have large mode areas and large separations between the propagation constants of its modes.

摘要： The invention relates to devices having periodic refractive index modulation structures and fabrication methods for the devices using a laser means. By focusing a pulsed laser beam into a transparent material substrate, a path of laser modified volumes can be formed with modified refractive index compared with the unprocessed material. By selecting appropriate laser parameters and relative scan speed, the laser modified path defines an optical waveguide. Separation distance of the individual modified volumes define a periodic modification pattern along the waveguide path, so that the waveguide structures also exhibit grating responses, for example, as spectral filters, Bragg reflectors, grating couplers, grating sensors, or other devices. This method of direct laser fabrication enables one-step fabrication and integration of periodic or aperiodic refractive-index modulation devices together with optical waveguiding properties to enable low-cost, multifunctional 1D, 2D or 3D optical circuit fabrication for simple and complex applications.
