Abstract

Optical frequency combs have revolutionized the fields of time metrology, frequency synthesis and optical spectroscopy. Recently, we experimentally demonstrated the feasibility of its phononic analogue in a micromechanical resonator. The underlying nonlinear process for this generation was via parametric three-wave mixing. Now, in this paper, utilizing three nominally identical copies of this device, we show the emergence of three distinct regimes viz. 'Two-mode phononic frequency comb'; 'Two-mode non-phononic frequency comb'; 'Three-mode phononic frequency comb'.
