Japanese scientists have learned how to control "light bullets", although still in simulation

Scientists from Japan conducted an almost "fantastic" experiment at the Institute of Laser Engineering of Osaka University, in during which they managed to control the so-called "light bullets" - localized pulses of electromagnetic radiation.

True, the experiment itself was staged not in "metal", but with the help of high-precision simulation, the results of which were published in the peer-reviewed journal Communication Physics. Remarkably, Zhaoyang Li and Yunzhi Kawanaka published their proof of the theoretical feasibility of "light bullets" only last summer.

What was implemented in the simulation

During the simulation, the scientists used a combination of deformable mirrors, a spatial radiation modulator and a beam splitter. The rays transmitted through such a virtual installation are converted into a certain shape of impulses, and the speed of their different sections in space directly depends on the shape.

By controlling the light bullets in this way, it is quite possible to calculate both the speed and their acceleration.

What are "light bullets"

The so-called "light bullets" are a very curious phenomenon that began to be actively discussed in 1990. The use of this phenomenon looks quite promising in many practical areas.

So it is assumed that through the use of light bullets it will be possible to implement completely new integrated circuits or create completely new principles for transmitting a data array.

In order to obtain a "light bullet", the pulse characteristics are carefully selected. Due to this, self-focusing and compensation of scattering in the medium will be provided.

When everything will be realized in reality

Of course, the simulation itself has significant limitations and, despite the sufficiently high simulation accuracy, it is not yet known how best to implement this experiment in reality.

Most likely, you will need to go a long way, during which you need to perform an accurate selection of materials for each node. installation and wavelengths of the emitted light, but, as scientists say, they are critical obstacles to a real experiment. do not see.

And given the speed with which scientists are progressing in the study of this issue, it will not be surprising that already this year they will be able to conduct a real experiment with light bullets.
