    摘要： The device is based on a cross-correlator which measures the signal between a pair of oppositely chirped laser pulses. Two laser pulses, one with a positive chirp and one with a negative chirp, are mixed on a beamsplitter. The two resulting beams pass through a reference or a sample arm and are subsequently mixed on a non-linear crystal. The signal from the interferometer is the sum frequency generation produced in that crystal. The reference arm contains a moveable delay which is used to change the relative timing of the two beams in the interferometer. The sum frequency generation in the narrow band of frequencies is the signal from the device and is measured as a function of the delay. Alternatively, a pure dispersive phase shift could be used in place of the two laser pulses.

    摘要： An interferometer and a method for generating scattered light interference are provided. A beam splitter is provided by a single metal nanoparticle to split an incoming excitation light. Scattered light from the single metal nanoparticle and its mirror image shows interference in both spatial and spectral domains. A mirror modifies the spatial distribution of elastic light scattering of the single metal nanoparticle. A large spectral width of the scattered light enables a distance measurement without scanning the mirror.

    摘要： A system for controlling a phase measurement in an atom interferometer comprising one or more lasers, a processor, and a memory. The one or more lasers are for providing interrogating beams. A first cloud of atoms and a second cloud of atoms traverse an interrogating region of the atom interferometer in substantially opposite directions. The interrogating beams interact substantially simultaneously with both atoms in the first cloud and atoms in the second cloud. The first cloud of atoms and the second cloud of atoms interact with each of the interrogating beams in a different order. The processor is configured to determine a phase adjustment offset of at least one interrogating beam based at least in part on one or more past interactions of one or more interrogating beams with either the first cloud of atoms or the second cloud of atoms.

    摘要： In one embodiment, an apparatus comprises an optical system with multiple detectors and a processor. The optical system is configured to produce images of an optical source in a first dimension and a second dimension substantially orthogonal to the first dimension at each detector at a given time. Each image from the images is based on an interference of an emission from the optical source in a first direction and an emission from the optical source in a second direction different from the first direction. The processor is configured to calculate a position in a third dimension based on the images. The third dimension is substantially orthogonal to the first dimension and the second dimension.

    摘要： In an atom interferometer, improved results are obtained by configuring the interferometer to have a baseline fringe pattern, in combination with spatially resolved measurements at the interferometer ports. Two aspects of this idea are provided. In the first aspect, the atoms are configured to expand from an initial point-like spatial distribution. The result is an informative correlation between atom position and interferometer phase. In the second aspect, a phase shear is applied to the atom ensemble of an atom interferometer. In both cases, spatially resolved measurements at the interferometer ports can provide enhanced interferometer performance, such as single-shot operation.

    摘要： An interferometer for controlling the coalescence of a pair of photons, including: an optical source, which generates a first and a second pump pulse coherent with each other and shifted in time by a delay; and a first interferometric stage, which receives the first pump pulse and generates an antisymmetric state with two coalescent photons (1/√{square root over (2)}(|21,02−|01,22)). The interferometer also includes a second interferometric stage, which receives the second pump pulse and generates a symmetric state with two coalescent photons (1/√{square root over (2)}·(|21,02+|01,22)), the first and the second interferometric stages being connected in a manner such that the interferometer outputs a final state equal to a weighted sum of the antisymmetric state and of the symmetric state (1/√{square root over (2)}·(|21,02+|01,22)+eiτ·1/√{square root over (2)}·(|21,02−|01,22)), the weights of the sum being a function of the delay.
