    摘要: An optical multiplexer is provided that includes a reconfigurable switching fabric with a number of inputs and outputs. In addition, the reconfigurable switching fabric employs VLSOAs that facilitate at least partial reconfiguration of the switching fabric by serving as switches to add, drop or pass-through one or more optical signals received at the inputs of the reconfigurable switching fabric. In some cases, one or more of the VLSOAs also serve to amplify one or more optical signals so as to compensate for losses that may be experienced by the signal in transit through the switching fabric, or elsewhere. Finally, this example of the optical multiplexer includes a wavelength division multiplexer coupled to the reconfigurable switching fabric and configured to multiplex at least some of the optical signals received from outputs of the reconfigurable switching fabric.

    摘要: Optical regenerators are disclosed, one of which includes a splitter having an input signal input, and first and second outputs, where the first output is connected to a first input of an optical flip-flop that also includes an output. A first OAND gate includes a first input connected to the output of the optical flip-flop, and also includes a second input and an output. A second OAND gate has a first input connected to the second output of the splitter, and includes a second input and an output. A variable oscillator having an input and an output is arranged so that the output is connected to the second input of the second OAND gate and to the second input of the first OAND gate. Finally, a feedback controller has an input connected to the second OAND gate output, and an output connected to the variable oscillator input.
