An 'all-optical switch' is a device that uses light to control other optical signals without the need for electrical conversion, saving both time and energy in optical communications. A research team ...

Researchers have reported a zero-dimensional metal halide that switches its fluorescence ON through two independent pathways: ...

With the proliferation of fiber-optic products containing interfaces ranging from Gigabit Ethernet to 10-Gbps SONET, the demand for optical testing capabilities is high. Unfortunately, so is the cost ...

Fujitsu Laboratories has unveiled a new optical switch technology that it claims uses half the power of conventional optical switches. The new optical waveguide switch uses photonics made from silicon ...

An all-optical fiber-optic switching device that maintains the signal as light from input to output. Traditional switches that connect optical fiber lines are electro-optic. They convert photons from ...
