    Abstract: An optical switching element includes a resonant reflection element and a driving unit. The resonant reflection element has a thickness portion functioning as a waveguide layer, with one surface in a thickness direction functioning as a total reflection surface and the other surface having formed thereon a fine periodic structure with fine asperities, the resonant reflection element resonant-reflecting light that is incident from the other surface and has a specific wavelength component. The driving unit varies a resonant wavelength of resonant reflection by varying at least one of a shape and a refractive index of the resonant reflection element.

    Abstract: A rotating apparatus includes a folded back elastically deformable portion including a first piezoelectric element for deforming a first elastically deformable portion and a second piezoelectric element for deforming a second elastically deformable portion, and the rotating apparatus rotates a movable portion around a predetermined rotation axis, by respectively applying first and second driving voltage signals to the first and second piezoelectric elements, to deform the first and second elastically deformable portions. First and second connection positions have a relationship of being relatively the same or symmetrical across all folded back structures. The first connection position is where a signal line of the first driving voltage signal and the first piezoelectric element are connected, and the second connection position is where a signal line of the second driving voltage signal and the second piezoelectric element are connected.
