The anisotropic magnetoresistance and saturation magnetic field of the Permalloy thin films (Ni0.81Fe0.19) sputtered on a nonmagnetic (Ni0.81Fe0.19)0.66Cr0.34 buffer layer were measured. The AMR variations of the films after annealing and the size effect of the AMR stripes after etching were emphatically studied, and a qualitative analysis was proposed through a statistic model. The simulation results agree with the experiments.

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.
