AN OPTICAL WAVELENGTH COMB GENERATOR DEVICE |
摘要 |
<p>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.</p> |
