Optoelectronic device with enhanced lateral leakage of high order transverse optical modes into alloy-intermixed regions and method of making same
Optoelectronic device undergoes selective chemical transformation like alloy compositional intermixing forming a non-transformed core region and an adjacent to it periphery where transformation has occurred. Activated by selective implantation or diffusion of impurities like Zinc or Silicon, implantation or diffusion of point defects, or laser annealing, transformation results in a change of the refractive index such that the vertical profile of the refractive index at the periphery is distinct from that in the core. Therefore the optical modes of the core are no longer orthogonal to the modes of the periphery, are optically coupled to them and exhibit lateral leakage losses to the periphery. High order transverse optical modes associated to the same vertical optical mode have higher lateral leakage losses to the periphery than the fundamental transverse optical mode, thus supporting single transverse mode operation of the device. This approach applies to single transverse mode vertical cavity surface emitting lasers, edge-emitting lasers and coherently coupled arrays of such devices. |

Strain capacitor energy storage devices and assemblies
Energy storage devices are disclosed that store both electrical and mechanical energies, making the total energy stored larger than either an electrical or mechanical means alone. The energy storage device is charged by the application of a voltage, which charges a capacitor to store electrical energy while simultaneously exerting a force on the mechanical system that deforms the mechanical system, resulting in mechanical energy storage. When the charged device is discharged, both the electrical and mechanical energy are extracted in electrical form. Its unique features include, but are not limited to, the potential for long lifetime, improved safety, better portability, a wide operating temperature range, and environment friendliness. Arrays of energy storage devices can be assembled in various configurations to build high capacity energy storage units. |

Process for flexible and shape-conformal rope-shape supercapacitors
Provided is a process for producing a rope-shaped supercapacitor comprising: (a) impregnating a first mixture of a first electrode active material (e.g. activated carbon or isolated graphene sheets) and a first electrolyte into pores of a first porous rod to form a first electrode; (b) encasing a porous separator around the first electrode to form a separator-protected first electrode; (c) impregnating a second mixture of a second electrode active material and a second electrolyte into pores of a second conductive porous rod to form a second electrode; (d) combining the separator-protected first electrode and second electrode form a braid or twist yarn; and (e) wrapping or encasing a protective sheath around the braid or yarn to form the supercapacitor. |

Feedthrough seal apparatus, system, and method
In various examples, a feedthrough seal apparatus is configured to seal an opening in a device. The device includes a case surrounding an interior space, the case including the opening therein to allow access to the interior space from an exterior of the case. The feedthrough seal apparatus includes a plug disposed within the opening of the case. The plug is formed from at least one of a polymeric material and an adhesive material. The lead wire extends through the plug, such that a first end of the lead wire is disposed within the interior space of the case and a second end extends from the plug to the exterior of the case. The plug is configured to electrically insulate the lead wire from the case. Some examples include a method of making the feedthrough seal apparatus. |

Multilayer ceramic capacitor and method for producing the same
A multilayer ceramic capacitor having inner electrodes containing at least one metal selected from Cu, Ag, Pd, Pt, Rh, Ir, Ru, and Os in an amount of 0.1 atom % or more that is dissolved in Ni and Sn to form a solid solution.
