Self-excited oscillation and synchronization of an on-fiber optomechanical cavity
, 2019 We study a fully on-fiber optomechanical cavity and characterize its performance as a sensor. The cavity is formed by patterning a suspended metallic mirror near the tip of an optical fiber and by introducing a static reflector inside the fiber ...

Advanced Materials, EarlyView.We report a multifunctional tapered optical fiber integrating a conformal micro‐resistance temperature detector (µRTD) for local, real‐time thermometry during optical stimulation. The platform combines light‐delivery and temperature sensing within a minimally invasive footprint, enabling detection of sub‐degree cortical heating under representative ...

The absorber in parametric and forced systems
Vietnam Journal of Mechanics, 1980 In this paper, we consider the action of the absorber in the parametric and forced system. If we connect the non-resonant absorber to examined system the frequency will be changed and the resonant oscillation disappears; the resonant absorber is ...
