Abstract: A sensor system comprises a laser source that emits a pump beam at a first wavelength and a probe beam at a second wavelength, and an optical means for receiving the pump and probe beams. The optical means is operative to generate a plurality of light beams, each having a different frequency, from the pump and probe beams. One or more cells receive the light beams from the optical means and allow passage of the light beams therethrough, with the cells containing alkali atoms. A dichroic filter is configured to receive the light beams from the cells. The dichroic filter separates pump beam light and probe beam light from the light beams. A detector array receives the probe beam light from the dichroic filter. The detector array includes a two-dimensional array of photosensors that map out transmission of respective light beams corresponding to the probe beam light through the cells.

Abstract: A continuously tunable radio frequency (RF) sensor system is provided. The system includes a pump laser system that includes first and second pump lasers, at least one frequency modulator to modulate frequencies of first and second laser light from the pump lasers to first and second select frequencies, a switch system to selectively pass one of the first and second laser light, an amplifier to amplify the passed laser light, a frequency doubler to double the frequency of the amplified laser light to generate pump light. A laser source lock system is in communication with the pump laser system to ensure a frequency of the pump light is referenced to atoms in a vapor cell and provide a probe light. The pump light and probe light are transmitted through the vapor cell. A detector measures the probe light that passed through the vapor cell.

Abstract: Techniques for reducing the bias error present in optical gyroscopes is disclosed. Such techniques include at least one path length adjustment member placed in an optical gyroscope resonator, which are configured to modulate the optical path length of the resonator so that bias errors attributable to the optical path length are shifted outside of the bandwidth of the optical gyroscope. In some embodiments, the at least one path length adjustment member includes a plurality of microheaters coupled to the resonator, in which case optical path length modulation is achieved by heating the resonator via the microheaters. Alternatively, a plurality of piezo-electric regions can be placed in the resonator, which enables optical path length modulation through electric field gradients applied to the piezo-electric regions.

Abstract: An optical resonator device, which can be implemented in a Brillouin laser, comprises a first waveguide ring resonator having a first diameter, and one or more second waveguide ring resonators adjacent to the first waveguide ring resonator. The one or more second waveguide ring resonators each have a second diameter that is less than the first diameter. The one or more second waveguide ring resonators optically communicate with the first waveguide ring resonator, such that an optical signal in the first waveguide ring resonator optically couples into the one or more second waveguide ring resonators. The one or more second waveguide ring resonators is configured such that when the optical signal resonates within the first waveguide ring resonator and the one or more second waveguide ring resonators, the optical signal within the first waveguide ring resonator is suppressed.

Abstract: A multilayer waveguide coupler comprising a first grating and a second grating is provided. Each first copropagating waveguide of the first grating has a first periodically modulated width. Each second copropagating waveguide of the second grating has a second periodically modulated width. The second grating is positioned so that a phase offset is present between the first periodically modulated width of the first copropagating waveguides and the second periodically modulated width of the second copropagating waveguides. The grating spaced distance and phase offset are selected so that light diffracted out of the first copropagating waveguides and the second copropagating waveguides in the first direction interferes constructively to form the first light beam and light diffracted out of the first copropagating waveguides and the second copropagating waveguides in the second direction interferes destructively.

Abstract: Systems and methods for direct measurement of imbalanced optical paths using entangled photons are provided. A system includes an optical source for generating a pair of simultaneously produced photons. The system also includes first and second emitter/receivers that emit first and second photons in the pair of simultaneously produced photons towards a first and second remote reflector and receives the reflected first and second photons along first and second optical paths. Further, the system includes a mode combiner for combining the reflected first and second photons into first and second output ports. Moreover, the system includes photodetectors that detect photons from the first and second output ports. Also, the system includes a processor that measures a difference in time delay between the first and second optical paths based on a time difference of arrival of signals from the photodetectors.

Abstract: Apparatuses and methods for a four port atomic gyroscope are disclosed. Because of its four ports, a four port atomic gyroscope has an output separate from an input so as to increase sensitivity of the atomic gyroscope. Thus, smaller changes in rotation rate around a center axis of an optical waveguide loop of the four port atomic gyroscope can be detected.
