57 ABSTRACT A crossbar switch (200) with bifurcated optical fibers (271,..., 286) having
equivalent ends connected to transmitters (251,..., 254) and receivers (261,..., 264) and …

An optical switch, particularly useful as a bistable cross connect matrix. Parallel input
waveguides and parallel output waveguides are formed on a substrate at perpen dicular …

In a method for forming one or more features in a thick-film ink deposited on a substrate, a
photoimagable material is used to define a negative of the one or more features on the …

An optical device, such as the switch, for controlling the passage of a light beam into and out
of an end face of a waveguide such as a glass fiber includes utilizing either a layer or drop of …

320 tering of the beam. One or more fluids may be provided to a channel or chamber and
exposed to an incident beam, and the proportion of at least one of a plurality of fluids may be …

The disclosed invention is directed to a thermal optical Switch that includes a Switch conduit
comprised of a first chamber and a Second chamber interconnected to the first chamber, a …

A closed-loop piezoelectric pump is disclosed for use in a fluid delivery system. The pump
housing includes a movable diaphragm that defines a pumping chamber within the pump …

An optical switch is disclosed for a system including signals carried over a plurality of optical
fibers. The switch comprises a first and second plurality of optical fibers with each of the …
