Abstract:
An optical device includes: an optical device body; a first transparent electrode film deposited on a light incident side; a second transparent electrode film so formed that the first and second transparent electrode films face away from each other; and a first ferroelectric film deposited at least between the first and second transparent electrode films, wherein the first ferroelectric film vibrates in response to a drive voltage applied through the first and second transparent electrode films.
