Abstract: The present invention provides an optical switch, a method of use thereof, and an optical communications system including the same. The optical switch may include a first substrate having an input mirror located thereon and a second substrate having an output mirror located thereon, wherein the second substrate is substantially parallel with the first substrate. In an advantageous embodiment, the optical switch may further include a retro-reflector located adjacent the first and second substrates and configured to redirect radiation from the input mirror to the output mirror.

Abstract: The present invention provides an optical switch, a method of manufacture therefor and an optical communications system including the same. The optical switch may include a mirror and a retro-reflector optically alignable with the mirror. In one advantageous embodiment, the retro-reflector is positioned with respect to the mirror such that it redirects radiation reflecting off the mirror at a given angle back to the mirror at the given angle.

Abstract: This invention relates to a polyolefin copolymer composition produced with a catalyst having a metallocene complex in a single reactor in a process for the polymerization of an &agr;olefin monomer with one or more olefin comonomers, and a molecular weight maximum which occurs in that 50 percent by weight of the composition which has the highest weight percent comonomer content. Preferably, the composition has a comonomer partitioning factor C pf which is equal to or greater than 1.10 or molecular weight partitioning factor M pf which is equal to or greater than 1.15. Preferred composition also have at least 0.01 long chain branches per 1000 carbon atoms along the polymer backbone. These compositions with reverse molecular engineering have superior properties and are easily processable due to the simultaneous presence of the association of high molecular weight with high comonomer content and of long chain branching.
