Abstract
An optical control device having at least two optical fibers arranged extremely adjacent to each other over a certain distance so that the optical fibers are optically coupled to each other. Among optical waves propagating in one of the optical fibers, a particular optical wave which is selected by the propagation constants of the two optical fibers and the propagation constant of an ultrasonic applied to the one optical fiber is transmitted to the other optical fiber.
