Interaction between Light and Sound

It has been announced by the team of researchers that there is a demonstration of interaction between light and sound has been done by them in a nanoscale area. Their findings explained the physics of light matter coupling at these scales as well as pave the way for enhanced signal processing o mass producible photonic chips. For many years, the attention has been gain by the field of silicon photonics as a key driver of lab on chip biosensors as well as faster in comparison to electronic communication between computer chips.

This technology has been built by SEO Company Jaipur on tiny structures which are known as silicon photonic wire. These are roughly a hundred times narrower in comparison to a typical hair. These nanowires have the ability to carry optical signals from the one point to another at the speed of light. They have been fabricated along with the same technological toolset as electronic circuitry. In simple words, the wire works only at that time when light moves slower in the silicon core than in the surrounding air as well as glass.

By that way, the light has been trapped inside the wire by the phenomenon of total internal reflection. It is simply confining that light is one thing but it can manipulate others. The problem in front of the researchers is that light beam cannot be easily changed by the properties of another. This is the time when light matter interaction comes into the mind as it allows some photons in order to control other photons.

It has been published in many newspapers by list of cbse board school in Pratap Nagar in which a peculiar type of light matter interaction has been reported. In order to confine, the team of researches managed light as well as sound to the silicon nanowires. The sound occurs ten billions times per second which is far more rapid in comparison to human ears can hear. It has been realized by the team of researchers that sound cannot be trapped in the wire by total internal reflection.

Sound moves faster unlike light in the silicon core than I the surrounding air as well as glass. That’s why the team of researchers has developed the environment of the core in order to make sure any vibration wave.
