Users typically have three kinds of keyboards to choose from, depending on the switch type: mechanical, magnetic (Hall effect), and optical. The type of switch you choose decides not only the bulk ...
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 ...
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.
A mechanical keyboard that uses infrared light and photoelectric switches to detect a key press. Keyboards with optical switches have a quicker reaction time than metal switches and have a longer ...
