摘要： 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 a loop 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, electro-hydrodynamic electrohydrodynamic pumping, magneto-hydrodynamic magnetohydrodynamic pumping, thermocapillarity, thermal expansion, dielectric pumping, and/or variable dielectric pumping.

摘要： Devices and methods utilizing dielectric pumping and variable dielectric pumping to move fluids through microchannels. Two fluids having dissimilar 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.

摘要： Optical devices and methods for attenuating, shuttering, or switching optical signals as found in telecommunications. A platform carrying a portion of a waveguide and residing in a plane of a substrate is tipped, tilted, twisted, or otherwise moved out of the plane of the substrate to divert the path of an optical signal or to change coupling between adjacent waveguides. The platform can be formed by etching a substrate while leaving one or more connection points between the platform and the substrate to hold the platform to the substrate.

摘要： A hybrid digital electro-optic switch has core and/or cladding areas that contain at least two different materials which undergo a change in their refractive index when an electric field is applied. One of the two different materials used in core regions, for example, has a change in refractive index that is less than the change in refractive index for the other material when the materials are exposed to the same electric field. A hybrid digital electro-optic switch functions by modulating the propagation constants of the eigenmodes of the switch with a voltage-induced refractive-index change, so that the propagation constants of the two materials are equal either in the presence or absence of the electric field. These electro-optic modulations change the evanescent coupling between the waveguides of the waveguide regions of the switch and transfer an optical signal that was input into one of the waveguides to a coupled waveguide. Compared to earlier digital electro-optic switch designs, the new switch has lower switching voltage, smaller device size, a sharper optical signal transfer, and wider manufacturing and use tolerances, and the switch can use a wide array of materials in its construction. The new switch can also be integrated with both the microstrip and coplanar traveling wave electrodes for very high speed photonic switching applications.

摘要： Disclosed is a hybrid waveguide structure, wherein a core or cladding has a hybrid section or "button" of a different optical property such as refractive index from the major portion of the core or cladding, respectively. The hybrid section can be made of a passive material or an electro-optic material. Methods of making a hybrid waveguide structure are also disclosed. These methods include rib-based methods and trench-based methods, and in either of these methods, a temporary filler is used in many instances to incorporate the hybrid section into the hybrid waveguide structure.

摘要： A method of removing contaminants from the surface is disclosed. The method comprises coating the surface with a surface active agent having a first surface energy and into which the contaminants are combined, applying thereover a higher surface energy colloidal sol and then allowing sufficient time for the first surface energy material with the contaminants combined therewith to migrate through the colloidal sol so as to remove the contaminants from the immediate vicinity of the substrate surface. The surface may then be treated by exposing it to an acid or base to remove the migrated surfactant layer thus removing the trace of contaminants.
