  • Patent number: 9784930
    Abstract: An optical interface device for optically connecting photonic devices to optical device along with methods of making. The method includes providing a glass support member that is either monolithic or laminated. A laser beam is used to write cores in the body of the support member. The support member includes a bend section and the cores generally follow the bend section and serve to define curved optical waveguides. The cores provide strong out-of-plane optical confinement, thereby allowing for strong bends and therefore a compact design for the optical interface device.

  • Patent number: 9759873
    Abstract: An embodiment relates to a method for manufacturing an optical module having an MCF and two connection components, and enables rotational alignment of the MCF to be implemented with high accuracy even in short-haul optical wiring. The MCF is arranged in a region between the two connection components while an end thereof projects from one connection component. As this arrangement state is maintained, array positions of cores in the projecting end are observed from a side face and the MCF is rotationally aligned by a rotation grasp jig grasping the projecting end to adjust the array positions of the cores, based on the observation result.

  • Patent number: 9753232
    Abstract: Embodiments include a fiber organizer comprising an optical interface having a plurality of optical interface-side fiber positions arranged in a linear array, and a cable-side interface having at least two pluralities of cable-side fiber positions each arranged in a linear array. The at least two pluralities of cable-side fiber positions are not collinear with each other, and in some embodiments define a two-dimensional array. A plurality of optical fiber paths extend between the optical interface-side and the cable-side of the fiber organizer such that each optical fiber extends between one of the optical interface-side fiber positions and one of the cable-side fiber positions. Because the transition from a compact bundle of fibers to a linear array occurs within the fiber organizer residing within the plug connector rather than the boot assembly, the boot assembly can be made more compact and ergonomic.

  • Patent number: 9746608
    Abstract: A novel optical assembly apparatus for coupling optical energy and a related method for creating the novel optical assembly apparatus are disclosed. In one embodiment, the novel optical assembly apparatus includes a high-index contrast waveguide constructed on a semiconductor die or another base substrate with an aligned optical coupling section, a grating coupler etched onto a surface, a micro mirror with an acute angle relative to the surface, and a waveguide taper that narrows an optical beam width. A light ray entered into the optical coupling section is redirected by the micro mirror to form a perpendicular ray entry angle with the grating coupler. The grating coupler then efficiently couples the light ray with the waveguide taper, which in turn narrows the optical beam width. The light ray may originate from a semiconductor die or from an optical fiber, which is purposefully aligned with the high-index contrast waveguide.

  • Patent number: 9739709
    Abstract: A chip-scale, reusable sensor can detect aromatic hydrocarbons, such as benzene, toluene, ethylbenzene, and xylenes (BTEX), rapidly in water without sample preparation. The device is capable of real-time, continuous monitoring for BTEX solutes, which diffuse into a film, such as a polymer, on the sensors surface. In operation, BTEX analytes concentrate in the film, causing an increase in refractive index, which modulates evanescent coupling into the chips integrated photodetector array. Integration of the photodetector array simplifies system instrumentation and permits incorporation of an on-chip photocurrent reference region in the immediate vicinity of the sensing region, reducing drift due to temperature fluctuations. In some examples, the chip responds linearly for BTEX concentrations between 1 ppm and 30 ppm, with a limit of detection of 359 ppb, 249 ppb, and 103 ppb for benzene, toluene, and xylene in water, respectively.

  • Patent number: 9733123
    Abstract: A connector assembly is provided for coupling optical fibers to a spectrometer. The connector assembly includes a plate having a slit defined therein and a ferrule that secures end portions of the optical fibers therein. The ferrule includes a forward end having an aperture that receives the optical fibers.

The plate recess orients the plate and the ferrule recess orients the ferrule within the connector assembly that includes a spring for imparting a force urging the forward end of the ferrule into contact with the plate to minimize an air gap between the plate and the ferrule. The spring and the alignment mechanism maintain the ferrule in an x-y-z, rotation, and/or an angular orientation.
