- 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 powers everything from communications to sensing, yet even tiny imperfections can scatter it and weaken signals. To address this, a team led by the University of Bath—working with the University ...

Physicists and chemists at Heidelberg University have realized a photonic microchip that is driven by light just as easily as ...

A new Stanford-designed optical amplifier uses energy recycling in a resonator to deliver strong, low-noise amplification with far less power.

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 ...

The role of light in our lives is both pervasive and primordial. Ultraviolet light probably had a role in the very origins of life, and light-driven photosynthesis underlies all but the most primitive ...

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 ...

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 ...
