Webfrequency combs. Phononic frequency combs correspond to a series of equidistant and phase-coherent frequencies [9-18]. These frequency combs generated when a resonant can be Figure 1: A strong off-resonance drive of the mechanical mode leads to an array of equidistant frequencies, referred to as a ‘phononic frequency comb’. WebNov 18, 2024 · Frequency combs are typically produced using light, but they can also be generated using mechanical vibrations, such that each spectral line corresponds to a different vibrational frequency. Unlike optical combs, these so-called phononic combs can be tuned in situ.

WebMay 24, 2024 · When the resonator is pumped with a single tone at a frequency close to the sum of the two mechanical modes, phononic frequency combs are generated close to each mechanical mode, under certain and repeatable pump frequency and power conditions. The phononic combs consist of a set of equally-distanced phase-coherent spectral lines; we ... 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. bind to domain windows 10
Phononic Frequency Combs in Stand-Alone Piezoelectric Resonators
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 WebApr 5, 2024 · The Artemis II flight test will be NASA’s first mission with the crew and will pave the way to land the first woman and next man on the Moon on Artemis III. Building on those early missions, NASA’s Artemis program will return humans to the Moon for long-term exploration and future missions to worlds beyond, including Mars. WebJun 2, 2024 · As an analog of the optical frequency comb, the phononic frequency comb has been demonstrated in mechanical resonators recently.
