Abstract
An optical cross-connect switch and manufacturing method therefor is provided which includes a planar lightwave circuit having a number of optical waveguides and trenches. The planar lightwave circuit has a first waveguide and a second waveguide that intersect the trench such that optical coupling between the first and second waveguides is dependent upon a presence of a fluid at an intersection of the trench with the first and second waveguides. A mounting base, having a channel and through openings provided therein, has fill tubes disposed in the groove and through openings of the mounting base. A reservoir pedestal having through openings provided therein and bonded to the reservoir pedestal with the fill tubes extending through the through openings therein to form a reservoir substrate. A bubble-forming element is disposed on a first surface of the reservoir pedestal, including patterning a plurality of leads on the first surface and a sealing/bonding ring bonds and seals the planar lightwave circuit and the reservoir substrate to form a reservoir having the bubble-forming element and planar lightwave circuit aligned such that the reservoir is in fluid communication with the fil…
