Working prototype light-based semiconductor chip has been built for 6G and 7G connectivity،
Conventional chips block signals in the wrong frequency range using microwave filters. On a light-based chip, adding a microwave photonic filter can help fine-tune the component, allowing it to connect to signals at specific frequencies. This is a big deal because it allows the component to capture more precise information.
In 2019, President Donald Trump tweeted about 6G for the United States.
Ben Eggleton, Vice-Chancellor (Research) at the University of Sydney, said: “Microwave photonic filters play a crucial role in modern communications and radar applications, providing the flexibility to accurately filter different frequencies, thereby reducing electromagnetic interference and improving signal quality. ,”
So, to reiterate, these prototype communications chips will offer much higher RF bandwidth capabilities, and with the microwave photonic filter, they will eliminate high-band interference, which is important because high-band frequencies high only travel short distances but have greater energy. capacitance which usually causes interference.
We still have at least seven years until 6G launches and this technology might not even be ready by then, or another breakthrough might be invented. Still, it appears that photonic light-based communications chips for mobile devices are something to watch.
