Rapid and fine control over the phase of light is demonstrated by transferring digitally generated phase jumps from radio-frequency electrical signals onto light by means of acousto-optic interaction, and the underlying mechanism elucidated. This technique was used to engineer optical phase noise by tailoring the statistics of phase jumps in the electrical signal, which was then quantified usin...

In this work, the performance of three kinds of integrated optical ring-resonator based slow-light structures for sensing applications is theoretically studied using the transfer matrix method and the complex transmission coefficient approach. Enhancement of sensing performance due to the slowlight phenomenon is quantitatively formulated. The modeling results show that using realistic structure...

Recent US military events have produced a desperate need for language data in languages which have previously been given very little attention. Data resources for languages of military interest are often unavailable or insufficient to adequately develop new technologies. Realizing this need, the Defense Language Institute Foreign Language Center, has created a language data distribution center,...

Quantum fluctuations in the radiation pressure of light can excite stochastic motions of mechanical oscillators thereby realizing a linear quantum opto-mechanical coupling. When performing a precise measurement of the position of an oscillator, this coupling results in quantum radiation pressure noise. Up to now this effect has not been observed yet. Generally speaking, the strength of radiatio...

A Structured-Light Enabled Nonlinear Interferometer In article number 2200967, Zhi-Han Zhu, Xiao-Peng Hu, Bao-Sen Shi, and colleagues describe a structured-light enabled nonlinear interferometer capable of superresolution measurement in real time. Such novel technique realized the first observation 12-photon de Broglie wavelength time by using only low-cost detector, providing promising new way...

A white-light fiber-optic interferometer working in the spatial domain, using a special three-peak-wavelength LED as a light source and one of the two arms of the Michelson interferometer as a strain sensor, is presented. Based on the Gaussian spectrum distribution function, a simple spectrum-decomposing method is used to describe the special three-peak-wavelength LED source. Experimental and t...

Here, we present a concept based on the realization that a complex medium can be used as a simple interferometer. Changes in the wavefront of an incident coherent beam can be retrieved by analyzing changes in speckle patterns when the beam passes through a light diffuser. We demonstrate that the spatial intensity correlations of the speckle patterns are independent of the light diffusers, and a...

We consider a subgroup of unitary transformations on mode light induced by Mach-Zehnder Interferometer and an algebra observables describing photon-number detector preceded the interferometer. explore uncertainty principles between such their usefulness in performing Bell-like experiment to show violation Clauser-Horne-Shimony-Holt (CHSH) inequality under physical assumption that distinguishes ...
