It would seem, at first glance, it is impossible to "recode" the flow of light into sound waves, because from the point of view of physics there is not so much in common between them. But scientists do the impossible over and over again. According to the editors of the journal Nature Communication, specialists from the University of Sydney were the first in the world to be able to convert light into sound. Such a mechanism will create a completely new type of storage media and can radically change the entire IT industry.
As you know, photons of light are very fast moving particles. Therefore, the transmission of encoded data using photonic charges is a promising development, because such memory modules and communication systems will speed up any process associated with the processing and transmission of data. It should be said that, despite the attractiveness of this technology, the process of analyzing, encrypting and decrypting "photon" data is extremely difficult. For these purposes, Australian scientists have developed a special chip that is used to recognize a light signal.
Once inside the chip, the light beam interacts with an electromagnetic wave emitted by the device itself. This interaction causes sound vibrations lasting on the order of 10 nanoseconds. Built-in sensors process the signal received from photons. As a result, the acoustic signal enters a special chip, where the received message is recognized, and at the output it again acquires a high speed, becoming light. The information recorded on the chip can be processed like a normal bit. If there is information - "1", and when it is not - "0". A more detailed description of the technology can be seen in the video from ScienceAlert, whose experts posted it on their YouTube channel.
