Abstract:
Various embodiments of the present invention are related to microresonator systems and to methods of fabricating the microresonator systems. In one embodiment, a microresonator system (200) comprises a substrate (206) having a top surface layer (204) and at least one waveguide (214,216) embedded in the substrate and positioned adjacent to the top surface layer of the substrate. The microresonator system also includes a microresonator (202,402) having a top layer (218), an intermediate layer (222), a bottom layer (220), a peripheral region, and a peripheral coating (224). The bottom layer (220) of the microresonator is attached to and in electrical communication with the top surface layer (204) of the substrate. The microresonator is positioned so that at least a portion of the peripheral region is located above the at least one waveguide (214, 216). The peripheral coating (224) covers at least a portion of the peripheral surface and has a relatively lower index of refraction than the top, intermediate, and bottom layers of the microresonator.

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 embodimentof the present invention, an encoder-demulriplexer comprises a number of input signal lines and an encoder (1304) that generates an n-bit-constant-weight-code code-word internal address (1320, 1506, 1704) for each different input address (1318, 1702) received on the input signal lines. The encoder-demultiplexer also includes n microscale signal lines (1306-1311) on which an n-bit-constant-weight-code code word internal address is out put by the encoder and a number of encoder-demultiplexer-addressed nanowire signal lines interconnected with then microscale signal lines (1306-1311) via tunneling resistor junctions, the encoder-demultiplexer-addressed nanowire signal lines each associated with an n-bit-constant-weight-code code-word internal adress (1320, 1506, 1704).
