ABSTRACT:
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.
