Abstract: An atom trap integrated platform (ATIP) comprises a substrate, a membrane, and a suspended waveguide. The substrate has an opening formed therein. The membrane extends across a portion of the substrate opening. The suspended waveguide is formed on the membrane such that the suspended waveguide extends from a first edge of the substrate to a second edge. A magneto-optical trap (MOT) is formed around the suspended waveguide by emitting a plurality of cooling beams and a repump through the substrate opening. Evanescent fields are established above the suspended waveguide by coupling two trapping beams through the suspended waveguide, which trapping beams are red-detuned and blue-detuned with respect to the resonant optical transition of the atoms. By forming the MOT within the evanescent fields, an evanescent field optical trap (EFOT) is formed.

Abstract: A photonic integrated circuit and a method for its manufacture are provided. In an embodiment, an intermetal dielectric layer, for example, a silicon oxide layer, is contiguous between an upper metal layer and a lower metal layer on a substrate. One or more waveguides having top and bottom faces are formed in respective waveguide layers within the intermetal dielectric layer between the upper and lower metal layers. There is a distance of at least 600 nm from the upper metal layer to the top face of the uppermost of the several waveguides. There is a distance of at least 600 nm from the lower metal layer to the bottom face of the lowermost of the several waveguides. The waveguides are formed of silicon nitride for longer wavelengths and alumina for shorter wavelengths. These dimensions and materials are favorable for CMOS processing, among other things.

The dispenser includes a frame; a body coupled to the frame and defining a cavity for receiving the flexible reservoir and including a bottom wall defining an opening; and a fitment acceptor at least partly received in the opening. The fitment acceptor includes forward and rearward sidewalls. A radius of curvature of the forward sidewall differs from a radius of curvature of the rearward sidewall. The radius of curvature of the forward sidewall and the radius of the curvature of the rearward sidewall correspond with radiuses of curvature of respective front and rear ends of a fitment of the flexible reservoir such that the fitment of the flexible reservoir is only insertable in the fitment acceptor in one relative orientation between the fitment and the fitment acceptor.

Abstract: An optical amplifier device employing a Mach-Zehnder Interferometer (MZI) that reduces the amount of residual pump power in the optical output of the amplifier is disclosed. The MZI amplifier employs two geometrically linear optical amplifier arms or two multi-spatial-mode racetrack optical amplifiers to amplify a signal with a pumping beam, with the signal output port having extremely low levels of residual pump power. The MZI optical amplifier is a silicon photonic integrated circuit, with all optical amplifiers, couplers, phase shifters, and optical attenuators formed of silicon photonic integrated circuit elements. The MZI optical amplifier may include one, two, or three MZI stages, and multiple MZI optical amplifiers may be used in parallel or sequentially to achieve higher overall signal gain or power. The MZI optical amplifier may employ Brillouin-scattering-based amplifiers, Raman-based integrated waveguide optical amplifiers, or Erbium-doped integrated waveguide optical amplifiers.

Abstract: A compact laser source and a single sideband modulator used therein is disclosed. The compact laser source includes a seed laser and one or more channels, with each channel generating one or more output laser beams having corresponding different wavelengths. The compact laser source can be formed in whole or in part on a single optical motherboard to thereby minimize space and power requirements. By employing the disclosed single sideband modulator, harmonics in the generated output laser beams can be minimized. The compact laser source finds application in an atom interferometer (AI) system, which may be used to measure gravity, acceleration, or rotation of the AI system.

Abstract: A method and apparatus are provided for controlling the phase shifts produced in a binary corporate tree network of the kind, e.g., that can drive a phased array for steering an optical beam. The method employs a novel phase-wrapping technique in which an entire layer of the binary tree is disabled when the phase added in that layer reaches 2?. With that technique, it is possible to economize on electrical control lines and on the use of electric power, while still maintaining the ability to produce arbitrary phases at the output of the tree network.

At least the polymeric waveguide, and in embodiments, also the silicon-based waveguide, is tapered with a shape that effectuates optical coupling to the silicon-based waveguide.

Abstract: In an electro-optical modulator, an electro-optical modulation layer is bonded to a cladding layer that overlies a substrate. A modulation zone waveguide is optically coupled to the electro-optical modulation layer and optically coupled to an I/O waveguiding structure embedded in the cladding layer. The I/O waveguiding structure is conformed to guide input light toward the modulation zone waveguide and to guide output light away from the modulation zone waveguide.

Abstract: A hybrid spiral waveguide geometry is proposed that exhibits essentially zero curvature (i.e., infinite bend radius) at the center of the spiral (similar to a Fermat spiral), with the curvature then increasing in value as the spiral moves outward. Advantageously, as the spiral moves away from the center, the spacing between adjacent waveguides quickly approaches a constant value (similar to an Archimedean spiral). This hybrid spiral structure has been found to allow for a high density waveguide to be created with lower loss and requiring a smaller size than many conventional spiral configurations and finds use in optical delay lines, amplifiers and arrayed waveguide gratings.
