A method and structure for an optical switch. A channel is housed within a solid material. Contacts coupled to the channel are further coupled to the solid material, while a plurality of piezoelectric elements are coupled to chamber and further coupled to a slug. Optical waveguides are coupled to the channel. The contacts are coupled to a plurality of liquid metal globules, wherein one or more of the plurality of liquid metal globules are coupled to a slug. One or more piezoelectric elements are actuated, causing the slug to be moved within the channel. The motion of the slug is operable to block or unblock one or more of the plurality of optical waveguides.
