Dependance of the Frequency of an Optically Injected Semiconductor Laser
Résumé
We show that contrary to what is predicted by the Adler's model, optical injection in semiconductor laser is accompanied by frequency pushing (the injected laser frequency is pushed away from that of the free slave). However, pulling may be observed at very low level of injection (1-10 nanowatt) when the laser is not saturated by the external field. We used the recently introduced laser transfer function to explain these observations.
