Abstract

We report the experimental observation of the squeezing effect in a graphene mechanical resonator due to an optical actuation force. We fabricate a circular suspended graphene mechanical resonator and measure two quadrature components of the mechanical mode via a phase-locked demodulation technique. By analyzing the correlated distribution of the two components, we find a squeezing effect when increasing the actuation power. We also observe singularity phenomena right at the cut-off frequency, which might be related to the nonlinear effect. Further study is needed to fully understand these phenomena. Our results might find new applications in the fields of sensing and mechanical information processing.
