摘要:
An electro-optical connector including a first connector end and a second connector end. The first connector end is coupled to a first electro-optical device. The second connector end coupled to a second electro-optical device. The second connector is flexibly coupled to a connector base so a second connector face can move flexibly with respect to a first connector face. A force mechanism on at least one connector end applies a force on an interface between the first connector end and the second connector end. The force is applied when the first connector face is within a predefined proximity of the second connector face. A mechanical guide on the connector end can align the first connector face with the second connector face when the force mechanism applies the force. The connector end for the force mechanism or the mechanical guide can be the first connector end or the second connector end.

A method for connecting a photonic crystal fiber having a plurality of cores connected to an optical device. An end of the photonic crystal fiber may be placed on a surface of an optical device having a plurality of coupling pads. A first core of the end of the photonic crystal fiber may be positioned over a first coupling pad on the optical device to enable a threshold amount of a coherent beam of light to propagate through the first core and first coupling pad. A second core of the end of the photonic crystal fiber is aligned to a second coupling pad on the optical device to enable a threshold amount of another coherent beam of light to propagate through the second core and second coupling pad. The end of the photonic crystal fiber may be adhered to the surface of the optical device while the position of the first and the second cores relative to the first and the second coupling pads, respectively, is maintained.

Various embodiments of the present invention are directed to demultiplexers that include tunneling resistor nanowire junctions, and to nanowire addressing methods for reliably addressing nanowire signal lines in nanoscale and mixed-scale demultiplexers. In one embodiment of the present invention, an encoder-demultiplexer comprises a number of input signal lines and an encoder that generates an n-bit-constant-weight-code code-word internal address for each different input address received on the input signal lines. The encoder-demultiplexer includes n microscale signal lines on which an n-bit-constant-weight-code code-word internal address is output by the encoder, where each microscale signal line carries one bit of the n-bit-constant-weight-code code-word internal address. The encoder-demultiplexer also includes a number of encoder-demultiplexer-addressed nanowire signal lines interconnected with the n microscale signal lines via tunneling resistor junctions, the encoder-demultiplexer-addressed nanowire signal lines each associated with an n-bit-constant-weight-code code-word internal address.

A switching device includes at least one bottom electrode and at least one top electrode. The top electrode crosses the bottom electrode at a non-zero angle, thereby forming a junction. A metal oxide layer is established on at least one of the bottom electrode or the top electrode. A molecular layer including a monolayer of organic molecules and a source of water molecules is established in the junction. Upon introduction of a forward bias, the molecular layer facilitates a redox reaction between the electrodes, thereby reducing a tunneling gap between the electrodes.

One embodiment of the present invention is an array of nanoscale latches interconnected by a nanowire bus to form a latch array. Each nanoscale latch in the nanoscale-latch array serves as a nanoscale register, and is driven by a nanoscale control line. Primitive operations for the latch array can be defined as sequences of one or more inputs to one or more of the nanowire data bus and nanoscale control lines. In various latch-array embodiments of the present invention, information can be transferred from one nanoscale latch to another nanoscale latch in a controlled fashion, and sequences of information-transfer operations can be devised to implement arbitrary Boolean logic operations and operators, including NOT, AND, OR, XOR, NOR, NAND, and other such Boolean logic operators and operations, as well as input and output functions. Nanoscale-latch arrays can be combined and interconnected in an almost limitless number of different ways to construct arbitrarily complex, sequential, parallel, or both parallel and sequential computing engines that represent additional embodiments of the present invention.
