Abstract
The present application relates to comb frequency generator devices generally and more particularly to the use of comb generators for use in fibre optic communications. More particularly, the application provides a frequency comb generator device. The device comprises a laser (30), a biasing circuit for providing a DC bias current (26), an RF circuit (22) providing a RF signal and a drive circuit (28) for combining the RF signal with the DC bias current to provide a drive current to the laser (30). With the DC bias current below threshold of the laser diode and RF bias with a frequence close to the relaxation ascillation frequency of the laser diode, a periodic pulse train is emitted with constant phase.
