Abstract :
The effect of phase conjugate feedback on semiconductor laser continues to be a topic of interest. Phase conjugate feedback has the advantage of self-alignment and aberration correction. These properties result in good coupling back into the laser, which is not guaranteed with conventional mirror. On the other hand, it has been demonstrated that the round trip phase delay for an external phase conjugate cavity is set by the laser and the phase conjugate mirror, independent of cavity length. In this presentation we consider the impact of this phase delay on the laser diode linewidth
