An array of permalloy core solenoids is micromachined as microactuators on (100) silicon wafer. Then anisotropic etching of silicon in KOH solution forms the U-grooves beside the microactuators. The micromachining difficulties from the coexistence of 3-D MEMS devices and deep grooves on chip are overcome successfully. Then two fibers and permalloy piece are assembled onto the wafer together with the microstructures finishing the prototype of the new type MEMS VOA. Third, the inductance, resistance and Q value of the microfabricated solenoids are measured in the frequency range of 1-40 MHz.

Then the MEMS solenoid type electromagnetic actuating and novel, frictionless and wear-free, and simple structure are designed for fiber-deflecting type MEMS VOA: One of the two coupled single mode fibers is completely fastened in one of the three aligned U-shaped grooves while the deflectable fiber is partially fixed in another groove with a long front section suspending over the wider groove as a cantilever beam. The two fibers, any one for input and the other for output, are well aligned initially so that the insertion loss is very low. Beside the deflectable fiber is a solenoid microactuator with a U-shaped permalloy core attracting a permalloy piece glued on side of the fiber cantilever so that the fiber is deflected and the optical power coupled between the fibers decreased continuously. Using MEMS solenoid as a continuous actuator and the novel structure of VOA are not seen in literature.
