From integrated photonics to quantum information science, the ability to control light with electric fields -- a phenomenon known as the electro-optic effect -- supports vital applications such as ...

Transferring optical information in free space with large bandwidth and high transmission capacity has gained significant attention in various applications, such as remote sensing, underwater ...

Current technologies to modulate light in free space are bulky, slow, static, or inefficient. Now researchers have developed a compact and tunable electro-optic modulator for free space applications ...

To foster in a new generation of high-speed communication, the main challenge is with the steps to transform electronic signals into optical signals rapidly. One company has recently made significant ...

To attain accurate positioning, a servo system requires a feedback signal to close its feedback loop. Instruments that typically supply the feedback signal include optical encoders, resolvers, and ...

Absolute encoders using optical technology often face limitations in resolution and size. For example, to achieve a higher resolution of up to 16-bits, the absolute encoder has to be combined with an ...

Last year, Automation World examined the differences between accuracy, resolution, and precision in the encoder world. And while understanding the differences among these terms is important to ...

An unexpected revisit to my earlier post on mouse encoder hacking sparked a timely opportunity to reexamine quadrature encoders, this time with a clearer lens and a more targeted focus on their signal ...

Electro-optic modulators, which convert signals from the electrical to the optical domain, are at the heart of optical communications, terahertz wireless communications, microwave signal processing, ...
