    摘要: A vacuum cell provides for electric field control within an ultra-high vacuum (UHV) for cold-neutral-atom quantum computing and other quantum applications. Electrode assemblies extend through vacuum cell walls. Prior to cell assembly, contacts are bonded to respective locations on the ambient-facing surfaces of the walls. Trenches are formed in the vacuum-facing surfaces of walls and via holes are formed, extending from trenches through the wall and into the contacts. Plating conductive material into the trenches and via holes forms the electrodes and vias. The electrodes are contained by the trenches and do not extend beyond the trenches so as to avoid interfering with the bonding of components to the vacuum-facing surfaces of the walls. The vias extend into the contacts to ensure good electrical contact. An electric-field controller applies electric potentials to the electrodes (via the contacts) to control electric fields within the vacuum.

    摘要: A technique is disclosed for electro-optically inducing a force to fabricated samples and/or devices with laser light. The technique uses the interaction of the oscillating electric field of the laser beam in opposition with the electric field produced by an appropriate electric charge carrier to achieve a net repulsive (or attractive) force on the component holding the electric charge. In one embodiment, force is achieved when the field near the charge carrier is modulated at a subharmonic of the electric field oscillation frequency of the laser and the relative phases of the light field and electric charge carrier field are controlled to provide optimal repulsion/attraction. The effect is scalable by applying the technique to an array of charge carrier fields sequentially as well as using higher power lasers and higher carrier field voltages.

    摘要: An atomic object confined in a particular region of an atomic object confinement apparatus is cooled using an S-to-P-to-D EIT cooling operation. A controller associated with the atomic object confinement apparatus controls first and second manipulation sources to respectively provide first and second manipulation signals to the particular region. The first manipulation signal is characterized by a first wavelength corresponding to a transition between an S manifold and a P manifold of a first component of the atomic object and detuned from the S-to-P transition by a first detuning. The second manipulation signal is characterized by a second wavelength corresponding to a transition between the P manifold and a D manifold of the first component and detuned from the P-to-D transition by a second detuning. The first and second detunings selected to establish a dark state associated with a two-photon transition between the S manifold and the D manifold.

    摘要: Embodiments of the present invention are directed to systems and methods for trapping and holding airborne particles. In the various embodiments, an optical trap is provided which uses a focused hollow-beam for trapping and holding both absorbing and non-absorbing airborne particles. The optical trap comprises: a trapping region where a particle can be present to be trapped; a light source for generating a coherent beam of light; optics for forming a hollow beam having a ring geometry from the coherent beam of light; and a focusing element for focusing the hollow beam to a point in the trapping region. In this arrangement, the particle is trapped at or near the focal point of the focused hollow beam.

    摘要: For manipulation of a specimen, the specimen and a focusing location of a composite material lens are brought into spatial coincidence. The composite material lens has at least one of a negative effective permittivity and a negative effective permeability at a frequency of an applied light beam. The composite material lens focuses the light beam toward the focusing location and forms an optical trap for the specimen.

    摘要: A method an apparatus for manipulating particles (micro, nano, and pico) having one or more characteristics with an optical trap formed by modulating a laser beam with a Diffractive Optical Element (DOE). At least one characteristic of the material is selected; and a laser beam having a selected wavelength corresponding to the at least one selected characteristic of the material is generated. Values of the DOE are calculated corresponding to the at least one selected characteristic of the material. The beam and the DOE are modulated to produce a holographic optical trap having properties corresponding to the at least one selected characteristic; the trap is focused to a beam focus or selected spot size; and the beam focus is located near a particle location for trapping the particle therein.
