摘要: The present invention provides nanometer-sized diameter silica fibers that exhibit high diameter uniformity and surface smoothness. The silica fibers can have diameters in a range of a about 20 nm to about 1000 nm. An exemplary method according to one embodiment of the invention for generating such fibers utilizes a two-step process in which in an initial step a micrometer sized diameter silica preform fiber is generated, and in a second step, the silica preform is drawn while coupled to a support element to form a nanometer sized diameter silica fiber. The portion of the support element to which the preform is coupled is maintained at a temperature suitable for drawing the nansized fiber, and is preferably controlled to exhibit a temporally stable temperature profile.

摘要: An N port fiber optical switch includes a movable housing having a perimeter and N corners; a plurality N of optical fibers positioned within the housing and inside the perimeter; and a plurality N of actuators, wherein each actuator is positioned on a corresponding corner such that when selectively activated one or more of the actuators urges the movable housing and the plurality of optical fibers to a selected switch position. The switch provides short switching times and high power handling while allowing for a large number of ports and provides the capability of interfacing with and switching between a variable number of ports.
