Abstract: Devices utilize elements carried by a fluid in a microchannel to switch, attenuate, shutter, filter, or phase shift optical signals. In certain embodiments, a microchannel carries a gaseous or liquid slug that interacts with at least a portion of the optical power of an optical signal traveling through a waveguide. The microchannel may form part of the cladding of the waveguide, part of the core and the cladding, or part of the core only. The microchannel may also have ends or may be configured as aloop or continuous channel. The fluid devices may be self-latching or may be semi-latching. The fluid in the microchannel is moved using e.g., e.g., electrocapillarity, differential-pressure electrocapillarity, electrowetting, continuous electrowetting, electrophoresis, electroosmosis, dielectrophoresis, electrohydrodynamic electrohydrodynamic pumping, thermocapillary, thermal expansion, dielectric pumping, and/or variable dielectric pumping.

Abstract: Devices and methods utilizing dielectric pumping and variable dieletric pumping to move fluids through microchannels. Two fluids having dissamilar dielectric constants form an interface that is positioned between two electrodes in order to move the interface and therefore the fluids. Dielectric pumping and variable dielectric pumping may be used to move fluids in miniaturized analytical packages containing microchannels in which forces created by surface tension predominate over the gravitational force.
