Abstract

We demonstrate analytically and numerically that multiple mixed external cavity mode solutions are possible for a laser subject to optical feedback from two external cavities. Such solutions exhibit a series of bifurcations and can be easily identified from optical spectra and their frequency content. Similar states have been proposed and analyzed within the framework of the usual Lang-Kobayashi equations describing a semiconductor laser subject to a single optical feedback in short cavities and with moderate pumping. We will present experimental results demonstrating the existence of mixed-mode states in a two-cavity system. We also find that the bifurcation sequence can terminate in low frequency fluctuation states before restabilization on a new maximum power external cavity mode.
