This study demonstrates a compact optical modulation platform that enables real-time, high-resolution spectroscopy using sub-MHz interleaved combs generated via chip-scale acousto-optic phase ...

Researchers have made a major advance in quantum computing with a new device that is nearly 100 times smaller than the diameter of a human hair. Subscribe to our newsletter for the latest sci-tech ...

Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS Complex modulation of optical fields (i.e., the control of light’s amplitude and phase) is vital to the ...

Physicists have engineered light to drift sideways in discrete, quantized steps inside a fiber-optic loop, reproducing a signature behavior of the quantum Hall effect without electrons, magnetic ...

Researchers have developed a holographic data storage approach that stores and retrieves information in three dimensions by ...

A major bottleneck with high-frequency wireless communications is the conversion from radio frequencies to optical signals and vice versa. This is performed by an electro-optic modulator (EOM), which ...

How a single silicon chip was designed to be microwave and optical signal-processing engine. The various roles for which this engine can be reconfigured. The performance considerations that were ...

Over the decades, development into silicon photonic modulators – technologically advanced devices that enable the manipulation of light properties – has revealed potential in various network and ...
