Abstract

We investigate the steady state and the dynamic behavior of a laser diode coupled to an external single-delay, 2 ns, Kerr cavity throughout the typical five feedback levels. We show that over a large range of feedback levels, for various Kerr constants, the steady state power dependent spectrum consists of one frequency which is shifted about 0.03 GHz from the solitary laser frequency. This is manifested by suppressing mode hopping at moderate feedback levels corresponding to level II. Similarly, coherence collapse is suppressed and its onset is shifted to higher feedback levels.
