摘要:
Various embodiments of the present invention are directed to optical broadcast buses configured with shared optical interfaces for fan-in and fan-out of optical signals. In one aspect, an optical broadcast bus (100,200,300) comprises a number of optical interfaces (121-123,210,212,216,218,301-303), a fan-in bus (102,202) optically coupled to the number of optical interfaces, and a fan-out bus (104,204) optically coupled to the number of optical interfaces. Each optical interface is configured to convert an electrical signal produced by the at least one node into an optical signal that is received and directed by the fan-in bus to the fan-out bus and broadcast by the fan-out bus to the number of optical interfaces. Each optical interface also converts the optical signal into an electrical signal that is sent to the electronically coupled at least one node for processing.

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 the n 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).

Embodiments of the present invention are directed to optical multiprocessing buses. In one embodiment, an optical broadcast bus (100) includes a repeater (106), a fan-in bus (102) optically coupled to a number of nodes and the repeater, and a fan-out bus (104) optically coupled to the nodes and the repeater. The fan-in bus (102) is configured to receive optical signals from each node and transmit the optical signals to the repeater, which (106) regenerates the optical signals. The fan-out bus (104) is configured to receive the regenerated optical signals output from the repeater (106) and distribute the regenerated optical signals to the nodes. The repeater (106) can also serve as an arbiter by granting one node at a time access to the fan-in bus.
