A rather groundbreaking development in chip architecture has recently emerged, which is likely to steamroll forward the telecom sector’s ambitions for moving ahead of 5G.

A hybrid of electronic and light-based components has now set the stage for 6G technology while also opening a new horizon for future generations of communication systems, including 7G.

The Next Leap in Communication Technology

Published on November 20 in Nature Communications, this research presents a visionary blueprint for the kind of communication chips that will be integral in advanced radar systems, satellite networks, and next-generation Wi-Fi.

What makes this development particularly noteworthy is the integration of photonic (light-based) components into traditional electronic circuits.

In layman’s terms, this combination will make chips better at handling a wider range of radio signals and more accurate at picking up high-frequency signals.

Building the Prototype: A Milestone Achievement

At the heart of this research lies a functional prototype of a networking semiconductor chip, modest in size at 0.2 by 0.2 inches, yet monumental in its implications.

Crafted from a silicon wafer, this chip integrates ‘chiplets’ – tiny units of electronic and photonic components – in a manner reminiscent of assembling Lego bricks.

Wireless transceivers, which are essential for sending and receiving data, usually use special filters in regular chips to block any unwanted radio signals.

In this new chip design, they’ve added a special kind of filter for light-based signals. The big achievement here is that they’ve managed to combine both light-based and electronic parts, along with these new filters, all on one chip.

This makes the chip good at picking up specific radio frequencies, especially those higher ones that often get crowded, and it helps the chip process information more accurately.

Implications for Future Wireless Technologies

The implications of this research are immense, to say the least.

Ben Eggleton, the leader of the research team from the University of Sydney, pointed out that these new microwave photonic filters are really useful for modern communication and radar systems.

He emphasized that these filters are great at picking out specific frequencies very accurately, which helps reduce unwanted signal noise and makes the quality of the signals much better.

This innovation is particularly pertinent as we move towards higher frequency ranges in wireless technology.

While 5G networks operate across a spectrum of frequencies, the advent of 6G, anticipated to become mainstream by the 2030s, will see operations starting from 7 to 15 GHz, as projected by the Global Systems for Mobile Communications Association (GSMA).

The utilization of photonics is crucial in this context, enabling mobile devices to function efficiently in mmWave bands above 30GHz.

Finally, the prototype chips created from this research are set to provide a much wider range of radio frequencies they can work with.

Adding a microwave photonic filter to these chips is a big deal.

It gets rid of problems in the high-frequency range.

These high frequencies can handle more data at faster speeds, but they usually don’t travel far and get easily disrupted.

The new chips can handle these frequencies better, making them more efficient.
