Fiber-aligning optical switch

摘要

A mechanical optical switch provides an active switching mechanism and an active latching mechanism that are both actuated by piezoelectric elements. The switching mechanism includes a switching frame at which fiber ends are attached to be switched along an opposing array of fixed fiber ends. The active latching mechanism provides for a fast switching of the switching mechanism and a reliable holding of the switching positions. The elements of the switching mechanism and the latching mechanism are monolithically fabricated from a wafer. The piezoelectric elements are integrated by bonding. The switch is substantially free of gliding friction, which reduces switching forces and makes the switch highly reliable over an extended lifetime.
