A tunable optical beamsplitter is disclosed that uses electrowetting
techniques to vary the propagation characteristics of one or more light
beams. Specifically, electrowetting principles are applied to a region of
fluid enclosed within an enclosure to form a plurality of liquid lenses.
When a light beam is incident upon the plurality of lenses, the plurality
of lenses transforms portions of the light beam in corresponding plurality
of output split beams. The region of fluid is controllably moved within
the enclosure to modify at least a first optical characteristic of at
least a first lens in said plurality of lenses in order to change the
propagation characteristics of at least one of the split beams.
