Abstract
Provided is a Fabry-Perot type wavelength tunable optical filter, comprising a first mirror; a second mirror located over the first mirror; a driving body located over the first mirror, and having both ends fixed to the first mirror through a spacer; a plurality of electrodes, each formed on both ends of the driving body; a rod structure connecting a center of the driving body and the second mirror; a plurality of fixing means, each fixed to the first mirror at both sides of the rod structure through the spacer; and a plurality of elastic bodies connecting the rod structure with the plurality of fixing means and acting as a rotational axis. And the mirror is driven by the rod structure acting as a lever that has an elastic body as a rotational axis, when warping is generated by electro-thermal expansion, electromagnetic force or external force. Thereby the mirror can be driven in the larger wavelength tunable range and the low power consumption.
