Abstract: A resonator for thermo optic devices is formed in the same process steps as a waveguide and is formed in a depression of a lower cladding while the waveguide is formed on a surface of the lower cladding. Since upper surfaces of the resonator and waveguide are substantially coplanar, the aspect ratio, as between the waveguide and resonator in an area where the waveguide and resonator front one another, decreases thereby increasing the bandwidth of the resonator. The depression is formed by photomasking and etching the lower cladding before forming the resonator and waveguide. Pluralities of resonators are also taught that are formed in a plurality of depressions of the lower cladding. To decrease resonator bandwidth, waveguide(s) are formed in the depression(s) of the lower cladding while the resonator is formed on the surface. Thermo optic devices formed with these resonators are also taught.

The discontinuities allow a section of the cable jacket to be pulled away from a remainder of the jacket using a relatively low peel force.

Abstract: An optical lens connector includes alignment features for passive connection alignment. The alignment features have generally planar surfaces to interface with a mating connector. The alignment features passively align an optical fiber with an optical lens in the optical lens connector, by fitting adjacent to planar surfaces of the mating connector. When interfaced together, the alignment features restrict lateral and vertical motion of the connectors with respect to each other, which helps keep the optical lens aligned with the optical fiber.

Abstract: A Periodic Cluster State Generator (PCSG) consisting of a monolithic integrated waveguide device that employs four wave mixing, an array of probabilistic Photon Guns, single mode Sequential Entanglers and an array of controllable entangling gates between modes to create arbitrary size and shape cluster states with several constraints. The cluster state is assumed linear or square lattice. Only nearest neighbor qubits are entangled. Such a cluster state resource has been proven to be able to perform universal quantum computing if the initial state is large enough.
