Spectrum collapse, narrow lines, and soliton combs with multi-frequency laser diodes locked to optical microresonators

摘要

We introduce a technique capable to produce and control stabilized single-frequency emission with a sub-kHzlinewidth and independently soliton comb generation from a multi{frequency regular Fabry-Perot laser diode selfinjectionlocked to a high-Q optical microresonator. We also observed novel regimes of controllable single, dual,and multiple-frequency generation that may be useful for the creation of narrow-linewidth lasers required for thespectroscopy, LIDARs, and telecommunications. For analysis of the considered effects original theoretical modelstaking into account self-injection locking effect, mode competition and Bogatov asymmetric mode interactionwere developed and numerical modeling was performed.
