Abstract
Circuitry and a concomitant methodology for generating a burst support signal to augment an input bursty optical signal in an optical channel. The burst support signal is produced whenever the input bursty optical signal falls below a predetermined threshold. The burst support signal is the result of self-oscillation of a semiconductor optical amplifier and a tunable optical feedback loop. The wavelength of the self-oscillation is determined by the operating characteristic of the feedback loop.
