Query: Mechanical Modulation of Hybrid Graphene Microfiber Structure   Recently, the strain engineering of two-dimensional materials such as
graphene has attracted considerable attention for its great potential in
functional nanodevices. Here, we theoretically and experimentally investigate
the strain manipulation of a graphene-integrated microfiber system for the
first time. We analyze the influential factors of strain tuning, i.e., the
geometrical parameters of the microfiber, the strain magnitude, and the
probe-light wavelength. Moreover, we experimentally achieve in-line modulation
as high as 30% with a moderate strain of ~5%, which is two orders of magnitude
larger than previous results. The dynamic vibration response is also
researched. The broadband, polarization-independent, cost-effective,
strain-based modulator may find applications in low-speed modulation and strain
sensing. Further, we believe that our platform may allow for all-in fiber
engineering of graphene-analogue materials and provide new ideas for
graphene-integrated flexible device design.
