We improved our electrostatic type switch to develop an electromagnetically operated fiber optic switch. A magnetic FeNi film was deposited on the mirror to make it controllable in a magnetic field. V-grooves were formed by the self-alignment technique to the mirror. Total size was reduced for faster switching speed and lower insertion loss.

The mirror could be latched at the ON or OFF states without a constant supply of energy thanks to the residual magnetism in the coil core used for the electromagnetic operation of the mirror.
