Abstract
A method of high frequency lightwave modulation based on the self-sustained pulsation (SSP) of laser diodes is presented. The microwave/millimeter wave frequency subcarrier is generated by the laser diode itself and can be tuned in a wide range by simply changing the DC bias. A theoretical mode has been developed and revealed the Hopf bifurcation is the origin of the SSP. The theoretical analysis also shows that the SSP may well exceed 100 GHz by properly controlling the device parameters. The SSP characteristics of the V-channeled substrate inner-stripe (VSIS) GaAlAs laser diodes have been studied both in the optical and microwave domain. The SSP frequency of the diodes can be tuned between 1-7 GHz. The modulation of the SSP generated subcarrier up to 1 GHz has also been demonstrated.
