Patent ID: 7009760

Claim:
An optical 3R regenerator, comprising: a splitter having a first input and first and second outputs, the splitter configured to receive an input signal at the first input; an optical flip-flop having a first input and an output, the first input being connected to the first output of the splitter; a first optical AND gate having first and second inputs and an output, the first input being connected to the output of the optical flip-flop; a second optical AND gate having first and second inputs and an output, the first input being connected to the second output of the splitter; a variable oscillator having an input and an output, the output being connected to the second input of the second optical AND gate and to the second input of the first optical AND gate; and a feedback controller having an input and an output, the input being connected to the output of the second optical AND gate, and the output being connected to the input of the variable oscillator.
