Patent number: 6598428Abstract: A method of producing an all glass, non-porous, multi-component photonic band-gap fiber is provided. The fiber is formed by creating a preform having a plurality of low refractive index glass rods and a plurality of high refractive index glass rods arranged in a pre-determined pattern between the low refractive index glass rods. The preform is heated and drawn to form the non-porous photonic band-gap fiber.Type: GrantFiled: September 11, 2000Date of Patent: July 29, 2003Assignee: Schott Fiber Optics, Inc.Inventors: Colm Cryan, Karim Tatah, Richard Strack

Patent number: 6585524Abstract: The present invention provides an optical interconnection device whereby arrays of fibers or waveguides arranged in a given orientation at an input side are rearranged in a three-dimensional rearrangement area within the device and exit at an output side arranged in a different orientation from the input side. Distinct arrays are created at the output side via manual or automated placement based on a roadmap.Type: GrantFiled: October 8, 2002Date of Patent: July 1, 2003Assignee: Schott Fiber Optics, Inc.Inventors: Matthew Scott Robinson, Richard Strack

Patent number: 6464404Abstract: The present invention provides an optical interconnection device whereby arrays of fibers or waveguides arranged in a given orientation at an input side are rearranged within the device and exit at an output side arranged in a different orientation from the input side. The method of accomplishing the rearrangement is to first arrange a plurality of ribbon fibers each containing a plurality of individual fibers. This arrangement is then fixed or secured at the output side to form a bundle. The output side bundle is then sliced in a different orientation, for example, in a direction orthogonal to each ribbon fiber at the input. As a result of the slicing, distinct arrays are created at the output side. Alternatively, distinct arrays are created at the output side via manual or automated placement based on a roadmap.Type: GrantFiled: June 19, 2000Date of Patent: October 15, 2002Assignee: Schott Fiber Optics, Inc.Inventors: Matthew Scott Robinson, Richard Strack

Patent number: 6442318Abstract: An optical fiber ribbon cable includes at least two optical fibers with their centers maintained in spaced relationship by at least one spacer fiber in abutting relationship with and between the optical fibers. The optical fibers and the at least one spacer fiber are maintain together and protected by an encapsulation layer. The optical fibers are made from a material that is relatively insoluble in at least one solution in which the encapsulation layer and the spacer fibers are relatively soluble. The optical fiber cable is connectorized to a multifiber terminal connector by dissolving the encapsulation layer and the spacer fibers along a some length of the ribbon cable, inserting the remaining optical fiber segments into corresponding fiber-receiving channels within the terminal connector and securing the fiber segments within the fiber-receiving channels.Type: GrantFiled: November 22, 2000Date of Patent: August 27, 2002Assignee: Schott Fiber Optics, Inc.Inventor: Paul D. Goldman

Patent number: 6243520Abstract: An optical fiber bundle having an aligned fiber array includes a plurality of optical fibers each of which has first and second ends and an axial fiber center. The optical fiber bundle has a first common end proximate to which the optical fibers are secured in place by a first array fixture such that a fiber segment adjacent the first end of each optical fiber protrudes from the first array fixture. Each fiber segment of a selected plurality of fiber segments belongs to at least one microspacer neighborhood that includes at least two fiber segments secured in contacting engagement with a precision microspacer installed between the at least two fiber segments such that the axial fiber centers at the first ends of the at least two fiber segments are maintained in predetermined array positions with respect to one another.Type: GrantFiled: August 16, 1999Date of Patent: June 5, 2001Assignee: Schott Fiber Optics, Inc.Inventor: Paul D. Goldman

Patent number: 5630784Abstract: The invention provides a rigid endoscope utilizing a high refractive index (HRI) tunnel rod, preferably made of glass, for transfer of image light from a distal end to a proximal end of the device, such HRI tunnel rod being modified so that a minimum of light is scattered and reflected within the rod, thus minimizing veiling glare and contrast reduction of the image which is formed near the HRI tunnel rod's proximal end. The HRI tunnel rod shortens the apparent distance from the proximal to the distal end by virtue of its refractive index being greater than that of air, and also provides a light tunnel which can carry the image over a relatively long distance by virtue of its modified inside walls. A preferred method of modification includes hydrogen firing of the HRI tunnel rod in order to create a thoroughly blackened inner surface which is highly non-reflective, even at grazing incidences.Type: GrantFiled: June 6, 1995Date of Patent: May 20, 1997Assignee: Schott Fiber Optics Inc.Inventors: Walter P. Siegmund, Paul W. Remijan, John M. Smith
