Since the conception of the laser frequency comb in the late 1990s, it has revolutionized the precise measurement of frequency and time. Beyond their initial use in optical clocks and precision ...
The Korea Research Institute of Standards and Science has successfully developed a length measurement system that achieves a level of precision approaching the theoretical limit allowed by quantum ...
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 ...
The challenge of achieving extremely high data rates via RF and optical links. How a hybrid RF/optical link was configured and deployed. The performance this hybrid link was able to provide.
A tunable metasurface can control optical light in space and time, offering a path toward new ways of wirelessly and securely transmitting large amounts of data both on Earth and in space. It is a ...
Figure 1 Schematic diagram of a nonlinear metasurface composed of asymmetric meta-atoms based on guided mode resonance and bound states in the continuum. Nonlinear optics is a branch of optics that ...
Copper cabling has been the workhorse for moving data inside of AI and HPC data centers, but fiber is nipping at its heels. Optics brings three possible bandwidth multipliers — wavelength-division ...
Modulation is the act of translating some low-frequency or baseband signal (voice, music, and data) to a higher frequency. Why do we modulate signals? There are at least two reasons: to allow the ...
