All-optical analog-to-digital conversion (AO-ADC) has a significant impact on future high speed optical communication and network systems, which hope to convert a continuous-time signal to a digital ...

Several years ago we were developing a clamp-on photometer, a hand-held instrument that could be clamped onto a communications optical fiber to indicate the presence of light, its direction of travel, ...

Precision instruments often contain specialized components that are essential to their function, but nearly impossible to replace if they fail. [Andre] had just such a problem with an optical ...

Traditional digital comparator ICs are electronic analogs of mechanical lever scales. Like their mechanical counterparts, they compare two logical signals and produce an output (typically a voltage ...
