Abstract

An optical switch unit has first and second elementary optical switches activatable by a single liquid droplet. The optical switch unit includes a first input and a first output. The optical switch unit may be included in an optical circuit that includes a plurality of inputs and a plurality of outputs, wherein at least one of the first and second elementary optical switches lies on a selectable path between a first input of the optical switch unit and a first output of the optical switch unit. A method of operating an optical switch unit includes changing states of first and second elementary switches by moving a liquid droplet, resulting in a change in switch state of the optical switch unit. The optical switch unit may include an elementary switch having two waveguides disposed horizontally and another elementary switch having two waveguides disposed vertically.
