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. WebWe find a threshold of PFC generation at V drv = 550mV and Vg = -6.4V, with relatively wide comb teeth spacing around 2.44 to 2.65MHz. At V g = -7V, the comb teeth spacing is reduced to 0.63MHz, exhibiting strong tunability of PFC.
