Caltech scientists have developed a way to guide light on silicon wafers with low signal loss approaching that of optical ...

- Development of the world's first practical surface-emitting laser suitable for optical fiber communications systems. - Utilization of quantum dots as an optical gain medium, enabled by NICT's ...

Light does a lot of work in the modern world, enabling all types of information technology, from TVs to satellites to ...

Researchers at the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) have taken a significant step ...

Nanolasers are ultrasmall laser devices with dimensions on the nanoscale. They generate coherent light through the process of stimulated emission, similar to conventional lasers, but at a much smaller ...

A large group of fiber optic lasers are powered by DC current. Laser drive is supplied by a current source with modulation added further along the signal path. The current source, although ...

Researchers have developed a new optical sensor that provides a simple way to achieve real-time detection of extremely low levels of arsenic in water. Researchers have developed a new optical sensor ...

Commercialization has started for network switches based on co-packaged optics (CPO), which are capable of routing signals at terabits per second speeds, but manufacturing challenges remain regarding ...

Brainiac75] is a fan of fiber optic lamps, except for one thing—they’re often remarkably dim. Thus, they set out to hack the technology to deliver terrifying amounts of light while still ...
