Query: Suppression of coherence collapse in semiconductor Fano lasers   We show that semiconductor Fano lasers strongly suppress dynamic
instabilities induced by external optical feedback. A comparison with
conventional Fabry-Perot lasers shows orders of magnitude improvement in
feedback stability, and in many cases even total suppression of coherence
collapse, which is of major importance for applications in integrated
photonics. The laser dynamics are analysed using a generalisation of the
Lang-Kobayashi model for semiconductor lasers with external feedback, and an
analytical expression for the critical feedback level is derived.
