  • Patent number: 9093810
    Abstract: A high efficiency electro-optic dendrimer based technology for nanophotonic integrated circuit devices is presented. In particular, a high power terahertz (THz) source is implemented using an electro-optic dendrimer via electro-optic rectification. Electro-optic rectification provides inherent power scalability, because, pump-THz conversion is not limited either by emission saturation or by heat dissipation. Low dielectric loss and high electro-optic coefficient of dendrimer along with a waveguide structure provides higher output power and tunable THz power generation. A dendrimer fiber array is also disclosed by means of which the input/output signals are connected to multiple components and devices.

  • Patent number: 8971674
    Abstract: An optical device with high thermal tuning efficiency is described. This optical device may be implemented using a tri-layer structure (silicon-on-insulator technology), including: a substrate, a buried-oxide layer and a semiconductor layer. In particular, a thermally tunable optical waveguide may be defined in the semiconductor layer. Furthermore, a portion of the substrate under the buried-oxide layer and substantially beneath a location of the thermally tunable optical waveguide is fabricated so that a portion of the buried-oxide layer is exposed. In this way, the thermal impedance between the thermally tunable optical waveguide and an external environment is increased, and power consumption associated with thermal tuning of the optical waveguide is reduced.

  • Patent number: 8953916
    Abstract: Multi-fiber, fiber optic cable assemblies and related fiber optic components, cables, and methods providing constrained optical fibers within an optical fiber sub-unit are disclosed. The optical fiber sub-unit(s) comprises optical fibers disposed adjacent a sub-unit strength member(s) within a sub-unit jacket. Movement of optical fibers within a sub-unit jacket can be constrained. In this manner, the optical fibers in an optical fiber sub-unit can be held together within the optical fiber sub-unit as a unit. As a non-limiting example, the optical fiber sub-unit(s) may be exposed and constrained in a furcation assembly as opposed to the optical fibers, thereby reducing complexity in fiber optic cable assembly preparations. Constraining the optical fibers may also allow optical skew, reduction of entanglement between the optical fibers and the cable strength members to reduce or avoid optical attenuation, and/or allow the optical fibers to act as anti-buckling components within the fiber optic cable.

  • Patent number: 8923668
    Abstract: According to the present invention, as a result of using a depressed or trench-assisted light-receiving waveguide in which the core is surrounded by a layer having a refractive index lower than that of a cladding as light-receiving means for receiving light outputted from a multi-core optical fiber, the layer of a low refractive index can inhibit the propagation of noise, etc. from the cladding to the core. Consequently, even in cases where the inter-core crosstalk is small, it is possible to accurately measure the inter-core crosstalk since components different from crosstalk-derived components in optical power are reduced.

  • Patent number: 8911161
    Abstract: Provided is a thermal mechanical diffusion system and method. In accordance with the present invention, one end of a fiber under tension is vibrated while a portion of the fiber is heated. A push-pull action of one end of the fiber forces increased (or rapid) diffusion of dopants in the portion of the fiber that is in a heat zone, which receives the heat. By controlling the amplitude and frequency of the vibration, a diffusion profile of one or more fibers can be dictated with precision. Heat sources having narrower thermal profiles can enable greater precision in dictating the diffusion profile. As an example, this can be particularly useful for creating a diffusion taper within a fiber to be spliced, where the taper is a result of thermal expansion of the fiber core. Diffusion can occur much more rapidly than is typical.
