Over the past decades, engineers have introduced numerous technologies that rely on light and its underlying characteristics.

Emerging, data-intensive technologies like artificial intelligence and machine learning are gaining popularity. Data centers, which act as the essential infrastructure for these technologies, need to ...

In radio communications, one way to generate single sideband (SSB) signals is to make a double sideband signal by feeding a carrier and a modulation signal into a balanced modulator to create a double ...

We recently saw how certain audio power amplifiers can be used as oscillators. This Design Idea shows how those same parts can be used for simple amplitude modulation, which is trickier than it might ...

Copper cabling has been the workhorse for moving data inside of AI and HPC data centers, but fiber is nipping at its heels. Optics brings three possible bandwidth multipliers — wavelength-division ...
