Paper Abstract

A two-axis magnetically levitated actuator is configured as an optical fiber micro-manipulator. Noise equivalent displacement capability of 0.01nm//Hz is demonstrated, with absolute positional stability of the order of 0.1μm°C, guaranteeing effectively perfect coupling of singlemode fibers to themselves and to thin-film waveguides. Freedom from mechanical stops allows coupling to 16 or more output fibers to effect a 5ms switching operation, and continuous coupling optimization under software control.
