摘要： The present invention provides process for fabricating an optical fiber assembly that includes two or more integral optical fiber elements having different interface characteristics, where at least one of the elements is a fiber optic device (fiber grating, in-fiber polarizer, coupler, mode filter, etc.), and where the length, and thus the cost, of each fiber optic device is advantageously optimized. The inventive process utilizes a two-stage approach, where at a first process stage, one or more optical fibers are spliced to one or more predetermined optical fiber device preforms (usable to fabricate one or more optical fiber devices), and where at a second process stage, one or more preform processing techniques (such as one or more of: drawing, twisting, etching, wrapping, etc.), are applied to the one or more preforms, to fabricate one or more corresponding optical fiber devices that are already integral with the optical fibers on one or both ends, thus forming the desirable optical fiber assembly. In another embodiment of the inventive process, multiple optical fiber assemblies can be readily and easily fabricated in a continuous process, by fabricating a single optical fiber assembly composed of multiple integral sequential desired optical fiber assemblies, and then separating the desired individual optical fiber assemblies from one another.

摘要： A multimode long period fiber Bragg grating (LPFBG) for a predetermined wavelength band. The LPFBG formed of a non-photosensitive material having an initial index of refraction. The multimode optical fiber core includes a substantially cylindrical surface, a longitudinal core axis, a core radius, and a number of index-altered portions having an altered index of refraction different from the initial cladding index of refraction. Each of the index-altered multimode optical fiber core has a first transmission surface and second transmission surface that is substantially parallel to the first transmission surface. Also, these index-altered portions are arranged within the non-photosensitive material of the multimode optical fiber core such that the first transmission surface of one portion of the plurality of index-altered portions is substantially parallel to the second transmission surface of a neighboring portion to form a long period Bragg grating structure.

摘要： A long period chiral fiber grating (nullLPCFGnull) that has a number of advantageous properties that can be readily utilized in a number of different applications is provided. The inventive LPCFG is a fiber grating having a pitch that exceeds the wavelength of light propagating therethrough. The LPCFG includes a number of dips in its transmission spectrum, but does not reflect any portion of the signal passing therethrough. The LPCFG is sensitive to changes in the refractive index of its external environment (or in the refractive index of a coating covering the LPCFG cladding). In response to changes in the external refractive index, the transmission dips shift proportionally to changes in the index, thus enabling the use of LPCFG as a fiber sensor element. In addition, the LPCFG is polarization sensitivenullone circular polarized wave of one handedness is coupled to the cladding mode stronger than the wave of the other polarization handedness. This enables the LPCFG to be readily utilized in polarizers and for shaping the polarization spectra of signals passing therethrough (in one embodiment configured as multiple LPCFG elements having different pitches). The polarization sensitivity of the inventive LPCFG can also be used for verifying system integrity in chiral fiber sensor systems. In other embodiments of the present invention, the novel LPCFG can be used for modulating amplitude of the light signal propagating therethrough, or as a resonant active structure for add/drop filters.

摘要： A single mode optical waveguide having reduced polarization mode dispersion and a method for making such a waveguide is disclosed. Perturbations are introduced into the waveguide core to couple power between the two polarization modes. A model calculation shows that the perturbation length may be of the order of the correlation length. The inventive waveguide is robust in that polarization mode dispersion is reduced even if perturbations are impressed on the fiber after manufacture.
