Abstract
Graphene resonators, characterized by small volume, low mass, high resonance frequencies and high quality factors, have attracted various attentions in recent years. In this work, two adjacent coupled graphene resonators were activated at the sum frequency <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\omega_{s}=\omega_{1}+\omega_{2}$</tex> , and the noise spectrums of the two resonators were detected through an optical interferometry method. Then the thermal motion of the two resonators projected into two quadrature phase space were recorded. The cross quadratures of the data indicated a correlation between the two resonators manifesting a squeezing effect, where the squeezing suppression ratio is calculated out to be around â4.46 dB.
