Earbuds are popular because compared to traditional on-ear or over-ear headphones, they’re unobtrusive, easy to carry and don’t restrict movement. Those advantages are boosted when you move to ...

A new filter with the widest tuning span ever demonstrated on a silicon chip could help provide the low-cost flexibility needed for the next generation of high-speed optical networks WASHINGTON - The ...

Scientists have developed a new filter with the widest tuning span ever demonstrated on a silicon chip that could help provide the low-cost flexibility needed for next generation of high-speed optical ...

The demand for 5G applications increases the need for radio frequency (RF) and microwave filter components in the mm-Wave frequency bands. The SynMatrix online interface with the AI-optimized tuning ...

The path toward an even faster internet has been hindered by energy consumption and cost per optical component. Researchers have designed a tunable filter -- an important component of high-capacity ...

The filter tuning is achieved with micro-heaters in the silicon chip that control the local temperature, which in turns affects the nanostructures and the frequencies they separate. The wide tuning ...
