WebThe generation of phononic frequency combs in the mechanical resonator described in [7,9,10,13] and shown schematically in Fig. 1a involves two steps. First, mode 1, which is a length extensional vibration mode, excites mode 2, which is a flexural vibration mode, when increasing the drive amplitude ( above a WebMay 22, 2024 · An optical frequency comb (OFC) is a spectrum consisting of a series of discrete, equally spaced elements with a well-defined phase relationship between them. The foundations of this breakthrough technology were laid in the works led by the co-recipients of the 2005 Nobel Prize in Physics John Hall and Theodor Hänsch.
