Title: Method of molecular-scale pattern imprinting at surfaces
Inventor: POLANYI JOHN C
IPC: H01L21/027
Filed: 2001-05-18
Abstract: A method for mask-free molecular or atomic patterning of surfaces of reactive solids is disclosed. Molecules adsorb at surfaces in patterns, governed by the structure of the surface, the chemical nature of the adsorbate, and the adsorbate coverage at the surface. The surface is patterned and then imprinted with the pattern by inducing localized chemical reaction between adsorbate molecules and the surface of the solid, resulting in an imprint being formed in the vicinity of the adsorbate molecules. When the imprinted molecular patterns are conjugated chains containing .pi. bonds along which electrical charge can flow the molecular patterns constitute molecular wires or the imprinted molecules constitute a molecular-scale device. The surface of the substrate can be doped by including n - or p- type dopants in the adsorbate molecules. These molecular wires are anchored to the substrate by using conjugated chains which can be chemically bound at intervals along the chains to the substrates.

Patent CA-2433381-A1 (CA)
Inventor: BESHAI MAGED E
IPC: H04Q11/00
Filed: 2003-06-25
Abstract: An optical core node that includes optical switching planes interfaces, at input, with multi-channel input links and, at output, with multi-channel output links.      The number of channels per link can differ significantly among the links, necessitating that the input (output) links have different connection patterns to the switching planes. Such an optical core node requires new methods of assigning an incoming wavelength channel to one of the optical switching planes. The assignment of the channels of input and output links to input and output ports is established in a manner that increases input-output connectivity and, hence, throughput. Additionally, the networks that may be formed with such optical core nodes require new routing methods. A preferred method of selecting a path through the core node favors switching planes connecting to a small number of links. In a time-division-multiplexing (TDM) mode, the method of path selection is complemented by temporal packing of TDM frames.
