Abstract: An optical ferrule assembly includes a hybrid optical ferrule having a glass portion assembled to a polymeric portion. The polymeric portion includes a groove for receiving and supporting an optical fiber having opposing open front and back ends. A light redirecting member includes an input surface for receiving light from the optical fiber and a light redirecting side. The open back end of the groove and the input surface define a recessed region therebetween. The glass portion includes an optically transparent glass insert disposed in the recessed region conforming in shape to an internal shape of the recessed region. An optical fiber is received and supported in the groove. The optical fiber includes a fiber end laser welded to the glass insert so that a central light ray from the optical fiber propagates through the glass insert before being received and redirected by the light redirecting side.

Abstract: A unitary optical ferrule is molded to include one or more elements for receiving and securing one or more optical waveguides one or more elements for affecting one or more characteristics of light from the optical waveguide while propagating the light within the ferrule. The optical ferrule also includes one or more first alignment features and one or more second alignment features that, when the ferrule is mated with a mating ferrule, each controls alignment of the ferrule with the mating ferrule along three mechanical degrees of freedom. The surface of the optical ferrule can be divided along the thickness axis into a first section and an opposing second section, wherein the first section of the surface includes the receiving and securing elements, the light affecting elements, and the first alignment features and the second section of the surface includes the second alignment features.

Abstract: A structured surface reduces optical reflectance at a predetermined wavelength in a first wavelength range extending from 600 nm to 1700 nm. The structured surface includes a plurality of parallel linear structures arranged along a first direction and extending along an orthogonal second direction. Each linear structure includes opposing nonlinear facets meeting at a peak extending along the second direction. An average spacing between the peaks of adjacent linear structures is less than the predetermined wavelength, such that for light having the predetermined wavelength and incident on the structured surface in a direction substantially perpendicular to the first and second directions, the structured surface has a reflectance Rx

Abstract: An optical metasurface film includes a flexible polymeric film having a first major surface, a patterned polymer layer having a first surface proximate to the first major surface of the flexible polymeric film and having a second nanostructured surface opposite the first surface, and a refractive index contrast layer adjacent to the nanostructured surface of the patterned polymer layer forming a nanostructured bilayer with a nanostructured interface. The nanostructured bilayer acts locally on amplitude, phase, or polarization of light, or a combination thereof and imparts a light phase shift that varies as a function of position of the nano structured bilayer on the flexible polymeric film. The light phase shift of the nanostructured bilayer defines a predetermined operative phase profile of the optical metasurface film.

Abstract: An optical cable subassembly includes one or more optical waveguides, at least light coupling unit comprising a first attachment area permanently attached to the optical waveguides, and at least one cable retainer comprising a second attachment area permanently attached to the optical waveguides and adapted to be installed in a housing. A length of the optical waveguides between the first attachment area and the second attachment area allows a bend in the optical waveguides that provides a predetermined mating spring force at a predetermined angle of the light coupling unit when installed in the housing.
