Advances in Phononic Devices pave way to Next-Gen Communication Tech

Have you ever thought about a microscopic component that can pave way to next-generation phononic devices, quantum computing, and sensors? Yes, scientists of this generation have helped conceptualize it.

A research group from Caltech, U.S., developed a unique component for mobile devices known as phononic devices. This device can move 10 million times per second back and forth, and is able to vibrate extremely fast.

Today, mobile devices use an acoustic wave to delay or filter communication signals. These built-in technologies have barred some further miniaturization of the device, which also restrains growth of communication bandwidths.

The researchers have invented 90-nanometer thick silicon nitride drums that will help manufacturers develop improved devices. The drum is arranged into grids with different grid patterns containing different properties. They figured out that by keeping the signal stronger by reducing interference the devices could behave like one-way valves for high frequency waves.

Some proven facts about phononic devices

The authors of the study say that waveguiding through a stable physical channel is strongly desired for reliable information transport in on-chip devices. However, they contended that energy transport in high-frequency mechanical systems is particularly sensitive to sharp turns and defects.

These phononic systems have proven the use of topological effects for quantum interfaces and lasing. Nevertheless, mechanical and acoustic topological systems are appreciated only in large-scale systems such as arrays of steel rods and arrays of pendula. So, let us see how this new venture will pave way for technological innovations of the future.
