Abstract: A method for aligning an opto-electronic component assembly (OECA) on a substrate includes positioning a substrate on an assembly surface and positioning an OECA on the substrate such that a first OECA alignment face projects from a first substrate alignment face. The substrate and the OECA are advanced towards a contact face of a first assembly alignment mechanism such that the first substrate alignment face contacts the contact face of the first assembly alignment mechanism after the first OECA alignment face contacts the contact face. The OECA is displaced relative to the first substrate alignment face when the first OECA alignment face contacts the contact face and the substrate continues to move towards the contact face thereby aligning the OECA on the substrate relative to the first substrate alignment face.

Abstract: A coupling for an optical device that disperses wavelengths along a focal line (30) includes reflective surfaces (34a-34e) that fold light out of a plane propagation and into alignment with an array of inputs (12) or outputs (14a-14e). Some of the reflective surfaces are offset from the focal line so that the inputs or outputs can be spaced closer together in a dimension along the focal line.

Abstract: A spherical lens formed by fusing a generally homogenous glass lens blank to the distal end of an optical fiber, heating and tensioning the lens blank to separate it in two segments with the segment attached to the optical fiber defining a tapered end, and heating the lens blank above its softening point so that the spherical lens forms. The lens blank is fabricated from a 4 weight percent borosilicate glass having a softening point less than that of the core of the optical fiber. The lens member defines a throat region adjacent the optical fiber whose cross-sectional dimension is substantially greater than the diameter of the optical fiber, but substantially less than the diameter of the spherical lens.

Abstract: Wavelength dispersion in an optical demultiplexer (10) is accomplished by varying propagation constants of a central pathway (16) traverse to the direction of wavefront propagation through the central pathway (16). The propagation constant can be varied by changing the dimensions or refractive qualities of the central pathway, which can be formed as a common waveguide (36) or as plurality of individual waveguides (16).

Abstract: Optical pathways along optical fibers, including multiple cores or multiple modes, are arranged with positive and negative dispersion characteristics. Coupling or connecting mechanisms regulate relative lengths of travel between the pathways having different dispersion characteristics so the total dispersion of the combined pathways approaches zero dispersion over a range of signal wavelengths intended for transmission.

Abstract: A unitary dispersion managed waveguide fiber with distributed amplification and a system incorporating the waveguide fiber are disclosed. Total dispersion along the waveguide fiber changes from positive to negative along the length of the waveguide over a transmission wavelength range. Distributed amplification is provided by stimulated emission of a dilute concentration of a rare earth dopant in the waveguide, by Raman effects or by both.
