Non-resonant operation of microcavity Brillouin lasers


We present theoretical framework to describe Brillouin lasing in microcavities in the case of a significant mismatch between the Brillouin shift and the cavity intermode spacing. We show that despite an increase of the lasing threshold a significant increase of the Brillouin power in comparison with the resonance case is achievable. A necessary condition for this effect is the optimal value of the pump frequency detuning from the cavity mode frequency. An increase of the Brillouin threshold is accompanied by narrowing of the spectrum range where the Brillouin signal could be generated in non-resonant case. Besides, with the optimal pump frequency detuning the Brillouin signal noise level is reduced. Analytical results are in quantitative agreement with the results of numerical simulations.
