  • MODE SIZE CONVERTERS AND OPTICAL ASSEMBLIES
    Publication number: 20160062039
    Abstract: One aspect of the invention provides a mode size converter having a first end and a second end. The mode size converter includes: a silicon waveguide having an inverse taper from the first end; and a silicon nitride waveguide having an inverse taper relative to the first end. The silicon nitride waveguide is adjacent and substantially parallel to the silicon waveguide. Another aspect of the invention provides an optical assembly including: a mode size converter as described herein; and a fiber optic optically coupled to the silicon nitride waveguide at the second end of the mode size converter.

  • Annealing bent optical fiber
    Patent number: 4812001
    Abstract: A method of forming an optical fiber elbow includes bending a straight optical fiber while subjecting the fiber to an elevated temperature for an amount of time sufficient to anneal strain out of the bent section of the optical fiber such that upon cooling the optical fiber maintains a bent attitude with little or no strain in the bend.

  • Contact for terminating an optical fiber
    Patent number: 4790622
    Abstract: An optical fiber contact for terminating an optical fiber includes a solid multi-part thermoset mixture in a cavity in a front portion of the contact, an optical fiber being terminated by heating the thermoset so as to cause it to soften and liquify and subsequently inserting an optical fiber through the contact. The thermoset when liquified chemically reacts so as to form an epoxy adhesive which secures the optical fiber within the contact and keeps the optical fiber in place even when subjected to extremely wide temperature variations.
