WebNov 27, 2024 · In this work, we show that there is a double frequency filtering based on two defect modes in an enormous gap by causing a defect at the segment level in the one-dimensional phononic comb-like structure, this is presented in Fig. 1(b). This structure has potential applications as acoustic filters or waveguides, etc. WebSep 16, 2024 · Abstract: Phononic frequency combs are mechanical response features evidenced as a series of equispaced discrete spectral lines. These features have been experimentally observed in a multitude of microelectromechanical devices confirming theoretical predictions of such phenomena in FPUT chains.
WebThe mechanical analog of optical frequency combs, phononic frequency combs, has recently been demonstrated in mechanical resonators and has been attributed to coupling between multiple phonon modes. This paper investigates the influence of the mode structure on comb generation using a model of two nonlinearly coupled phonon modes. 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.
WebIn the phononic frequency comb demonstrated in [3], the three-wave mixing process is particularly operative in the system of two parametrically coupled phonon modes. However, the preceding theoretical work [4] on frequency combs have actually shown the possibility for frequency combs in a system comprising three and four parametrically coupled ...
