Abstract
An electrostatic optical fiber switch. An aperture in the switch housing allows for switching movement of the end of a fiber. This aperture is formed in part by a groove in which the depth and width of the groove increases continuously with distance toward the end of the fiber. This forms a smoothly curving surface for restraining and aligning the switching end of the fiber when the electrostatic field is applied. This arrangement substantially reduces the voltage required to operate the switch by prior electrostatic switches.
