The purpose of optical antennas is to convert the energy of free propagating radiation to localized energy, and vice versa. Although this is similar to what radio wave and microwave antennas do, ...

PhD candidate Zixi Li at the UChicago Pritzker School of Molecular Engineering is the co-first author on a new paper from the lab of Asst. Prof. Alex High, which demonstrates a new way to provide more ...

Physicists from the University of Würzburg have converted electrical signals into photons and radiated them in specific directions using a low-footprint optical antenna that is only 800 nanometers in ...

In the need for a more compact and efficient optical phased array with a wide steering beam for LIDAR applications, a wide steering array with high resolution is desirable. However, in the published ...

Integrated optical phased arrays (OPAs) have emerged as a promising technology for many applications due to their ability to dynamically control free-space optical beams in a compact and ...

A multi-institutional team has created atomic optical antennas in solids. The team used germanium vacancy centers in diamonds to create an optical energy enhancement of six orders of magnitude, a ...

For the first time, physicists have successfully converted electrical signals into photons and radiated them in specific directions using a low-footprint optical antenna that is only 800 nanometers in ...
