Abstract: A system can include an optical multiplexer to combine a plurality of optical input signals having respective wavelengths into a wide-channel optical input signal that is provided to an input channel. The system also includes a photonic packet switch comprising a switch core and a plurality of ports defining a switch radix of the photonic packet switch. The input channel and an output channel can be associated with one of the plurality of ports. The photonic packet switch can process the wide-channel optical input signal and can generate a wide-channel optical output signal that is provided to the output channel. The system further includes an optical demultiplexer to separate the wide-channel optical output signal into a plurality of optical output signals having respective wavelengths. The optical multiplexer and the optical demultiplexer can collectively provide the system with a radix greater than the switch radix.

Abstract: Various embodiments of the present invention are directed to methods and systems for transmitting optical signals from a source to a plurality of receiving devices. In one method embodiment, an optical enablement signal is transmitted from the source to the plurality of receiving devices. The target receiving device responds to receiving the optical enablement signal by preparing to receive one or more optical data signals. The source transmits the one or more optical data signals to the target receiving device. The remaining receiving devices do not receive the one or more optical data signals.
