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 ...
A direct modulation bandwidth of 66 GHz has been achieved from two daisy-chained VCSELs, and the principle could be scaled up to reach over 100 GHz. An international research team has shown that a ...
As optical bandwidth requirements increase, system designers are turning to “coherent” modulation schemes that can place more data on the same laser light, and lower power over long connections. A ...
Ever increasing data-transmission speeds coupled with the need to contend with higher-order modulation schemes are presenting optical-communications test-and-measurement challenges. Products ranging ...

Researchers have developed a new design of vertical-cavity surface-emitting laser (VCSEL) that demonstrates record-fast temporal bandwidth. Researchers at the George Washington University have ...
High-speed analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) typically are characterized using continuous wave (CW) signals. There are several reasons for this practice: 1) ...
Multiphase buck topology is preferred for processors that are drawing increasing amounts of current at lower voltage. Common design practices limit the open-loop bandwidth of the control system to 10% ...
