Can light cast a shadow? It sounds like a tricky riddle, but researchers have shown that, under special conditions, a laser ...

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 ...

Plasmonic structures exhibit a wide range of physical characteristics, which are benefited by the localized and intensified ...

A device called an all-optical switch could instead use light to control other light signals without the need for electrical ...

Mechanical switches have long been the standard in keyboards, relying on physical contact to register key presses. However, ...

Some fiber optic switches can be used for both single mode and multimode ... The insertion loss is the attenuation caused by the insertion of an optical component. Polarization dependent loss is the ...

So far, researchers have looked into using nonlinear bistable materials as the basis for all-optical switches, but switching response times of such devices have not been investigated thoroughly.

Q-switches are devices used in the optical resonator of a laser to prevent lasing action until a high level of inversion is achieved in the lasing medium. There are many types of Q-switches. Examples ...
